3^rd  Icean Congress with

DevCon (Developer’s Connect)

September 7, 2011

OVERVIEW

It was almost one year ago, when a the collaboration between the class of Field Trip and Seminars, Society of Information Technology Students (SITS), and Computer Science Society (CSS) fruited as the 3^rd Icean Congress with DevCon (Developer’s Connect) was successfully held at the USeP Social Hall last September 7, 2011.

The said congress was attended by the students of Institute of Computing and students of related courses from others schools like Ateneo de Davao University, MATS College of Davao, Jose Maria College, University of Mindanao, Holy Cross of Davao College, and AMA Computer College. It was considered as one of the biggest gathering of information and technology studies here in Davao. The congress was celebrated together with the software freedom day. So, it is predectable that the main topic of the seminar is promoting the use of open-source softwares instead of using pirated and unlicense softwares.

The program was opened with remarks from Engr. Val A. Quimno, Dean of the Institute of Computing, who talked about the how the event is important to the students. Then, an awarding of the Certificate of Recognition was also held given to all the students of the Institute of Computing who gathered an GWA of 2.0 or higher from the last semester. It was great recognition for them but sorry for me, because I’m not of them. However, it make me motivate to strive more harder to achieve high grade and gain respect as what they have got. Afterwards, the 4^th year Computer Science and Information Technology students presented their Thesis Proposal and IT Project, respectively.

After the lunch break, the DevCon seminar was officially started by having lightning talks with different topics. Irwin Rod Adesna, a 4^th year ICean student, talked about the “Sex of Ideas” or the collaboration between two or more persons to create a more productive and quicker solution to a problem. The another lady speaker from the MATS College of the Davao talks about the Open Source Programming Utilities, she emphasize that it is no need to use the pirated software especially in university computer laboraty if there are lots of free equivalent software available. She also promotes an open-source computer laboratory that the universirty must have. The other speakers also  talked about Open Street Map, Content Management Systems, Android Technology, and Networking. All speakers, intruduce an new and realible open softwares in connection of the celebration of software freedom day.

Another part of the seminar was a friendly debate between three teams, it is  called Birds of Feather (BOF), was conducted to know which among Windows, Mac, and Linux the best operating system is. Three team done good that able to convince the listeners why kind of operation system they represented is better than other. Afterwards the announcement of winners, the team of Windows was hailed as the champions and the distribution of certificates and closing remarks finished the program successfully.

 Major Field Trip and Seminars 

Sept. 10 – 14, 2012

 Manila 

Field Trip Overview

            Last September 10 – 14, 2012 we conducted our major field trip in Manila together with my fellow students from Institute of Computing in Southeastern University of Philippines. The said field is one of our requirements for the subject of Field Trip and Seminar under our current curriculum. The purpose of the conducted field trip and seminar is the following:

·         To enrich our knowledge especially in field of computing

·         To engage in the modern technologies that are not present on our environment or university

·         To know further what are the profession we have in the future

·         To know the areas that computing is very important

The field trip in Manila was approved by our university president, and manages by one of our professors Mr. Randy Gamboa. We have departed from Davao by 6:45 in the morning of the first day of our schedule, and then we arrive back here in Davao by almost 8:00 in the evening on the last day of our schedule. We have spend five days and four nights in Manila, some say the it was that short to stay, and other say that it was too long. However, in the bottom part, our major field satisfies our all expectation and meets its purpose. It was a great success because we have learned a lot, and all destinations are very educational.

Day 1 (September 10, 2010) at DOST and MMDA

Today, I went on to two company visit; one is in the Department of Science and Technology and another one is in the Metropolitan Manila Development Authority.

In Department of Science and Technology, one of their staff guides us in their Audio Visual Room. In there, they showed us their latest project such as the Project NOAH (National Operational Assessment of Hazards) that under development but still very useful for the warnings of upcoming calamities.

What I Learned?

            What I learned from the Department of Science and Technology is that the government does exert effort to support the inventions, project and research for the good of the public. The Department facilitates the endorsement of the project to the public, and they also support for the further development. They used modern technology to connect the braches all over the Philippines.

What I Liked?

            What I liked from the Department of Science and Technology is the site they facilitate or hosted, the site is a compilation of database from all educational sites in the Philippines. The site makes the users to find related research on the interest topic by searching using the site.  

What I didn’t like?

            What I didn’t like is when we ask complex question regarding the Project NOAH and other project they facilitate, they always answer us that they only host the project and the group that has more knowledge about the project is not them but the author of the project. It makes me mad of getting nothing information of their some projects.

            In the afternoon, the Metropolitan Manila Development Authority is the company we have visited The MMDA serves the whole manila with over sixteen cities. In their office they have nine big monitors in their office that they used to keep update on the happening of over the Metro Manila.

What I Learned?

            What I learned from the Metropolitan Manila Development Authority used technologies to guard metro manila from extreme flooding using their pumping station with monitoring in their office. The MMDA also ensure the properness of the streets, they installed numbers of CCTV and record it in their database for evidence of violation or incidence.

 What I Liked?

            What I liked about the MMDA is that they have big monitors, large database storage, and moral officers. They used modern technologies to strengthen their service to the public. It makes them empowered and ready for the calamities that may strike in the metro manila.

What I didn’t like?

            I think I don’t have things that I didn’t like about the Metropolitan Manila Development Authority, their accommodation for us is fine, their service for the public is great, their technology are incredible. However, MMDA must not satisfy on what they have, the technology is rapidly changing so they must upgrade like adding an automatic license detection and recognition.

Day 2 (September 11, 2012) at UP-Diliman for Y4IT seminar

On our day two in Manila, have the visited the Diliman Campus of University of the Philippines. Comparing the campuses of USEP-obrero and UP-diliman, I think my university is just not half or even more half of UP campus. However, when it comes to the intelligence, USEP is near to UP, I can say that because I am USEP and I am proud to be.

We spend whole day on UP-diliman that was the host of the seminar of Information Technology students all over the Philippines. The seminar is called Y4IT and it was its tenth year so it was expected that more students will come for the seminar.

In the morning session, we have come to the UP-Diliman campus on time, but because there is huge number of participate of seminar there is no vacant seats for the interesting topic about the robotics and programming. As a result, we are not able to join the seminar on the said topic. Then, we find another seminar, and the seminar we have found is about the animation and current trends.

During the start of the seminar, we have surprise that our facilitator Mr. Randy Gamboa came up to the stage and speak to the mass. Oh, Mr. Randy is the one who welcome the seminar participant; this makes us proud that we are the students of the great guy on the stage.

While the Afternoon session, we had a chance on having a seat in the UP-theater where comfortable chair awaits us. UP-theater is dark, a best place to sleep; best time to restore our energy from the traveling using airplane for the first time.

What I Learned?

            One of the lady speakers grabs my attention not because of her sexy body but because of idea she what to deliver, she said the there only three things that the person has to success: tibay ng loob, talas ng isip, at kapal ng mukha. Yes, I definitely agree with her, it makes me encourage of dreaming becoming a successful programmer. She also added that when I expect something happen of improvement for myself, it will be granted only if I believe. What she says is more than anything what I have learned on the seminar.

What I liked?

            I really like about UP-diliman and the Y4IT seminar is the environment. Stepping on the ground of one the top university makes me like the moment. That is why we are very eager to go on their COOP, to buy souvenir for myself.

What I didn’t like?

            The thing I didn’t like is about the communication to the other student all over the Philippines. We are there for seminar to learn, not to prove that we are better to each other. Some other student feels arrogant, however, not all of them participants. 

After our visit in UP-diliman campus for Youth for Information and Technology Seminars, the itinerary schedule us to go shopping on one of famous mall in metro manila. Just what others say “Work with no play, makes me dull”, I really don’t know about the saying but what I wanted to emphasize is the fact that we have already in manila why we don’t maximize our time of spending it in fun way. However, the shopping on the second night of our field trip in Trinoma makes my unforgettable experience, because of the weird and big structure of the Trinoma building. I was lost in the exit of the mall that result of being late of almost twenty minutes on our scheduled dinner. Again guys, sorry for being late.     

Day 3 (September 12, 2012) at PLDT and SSS

In the third day of field trip and seminars, we have visited the Philippine Long Distance Telecom Company or the PLDT. In the third day, we have decided to go early in the company that we are going to visit. As a result we come there too early that we need to wait almost one hour in the bus to accommodate us. That the waiting is not for waste, the learnings we have got from the PLDT from the time we’ve enter their building up to we have exit is very substantial. All things are inside very interesting from the booths that display their history, room for internet monitoring, up to the device they invented to make the life of Filipinos more comfortable.

In the first part our PLDT company visit, the vice director of Community Relation Division welcome us by giving a name tag and brief presentation on what PLDT offers. It also tackles the brief history of the PLDT, from the small company and become bigger. But the rise of their company came to stop when the war was entered in the Philippines, lots of their infrastructure was bomb. However, the company still serve the public by providing each house the line of telephone. Then, the company starts to develop and fix the damage they got, and the success was in there. Up today, PLDT makes a partnership in Smart for providing the wireless internet connection.

What I Like?

            There are many interesting things that I liked inside the PLDT building, some of those are the ACER display room and room where the gadget offered by PLDT are being displayed. In ACER, the representative of ACER introduce their latest models of laptops, computers, and projectors.  I really like the war room of the PLDT that facilitated by at least four persons, they do monitoring on the Internet Traffic. In there we can see the total moment of upload and download done by all users over the Philippines. They also explain the technology behind the Virtual Private Network that it has physical wires just like what they offer in the public connection. But VPN is a secured channel where not all internet users can access.

What I didn’t like?

            The thing I just don’t like is that the ACER didn’t make raffle for the prize of a laptop. Are they cheap? Or are we not worthy to be given the prize.

On the other hand, while in the afternoon schedule, we’ve go to the company visit and it is in the Social Security System. On there, they conducted a symposium type of discussion where the speaker tackles about the history of SSS, its infrastructures and technologies used to deliver their service, and how their system is being secured.

After the speakers have presented they open the discussion for question, at first we are shy to ask question to them because many of us doesn’t care about the pension of SSS. But, somebody start to question about the technical part of SSS, and another question came out until the speaker get tired or don’t have enough time to answer our questions. Actually, our main concern is about on how the SSS enforce people especially who work in Business Process Outsourcing market to pay their obligations.

What I have learned?

            I have learned that even government doesn’t have supercomputers to handle their services just like big companies. Although, I understand that government doesn’t have enough budget to sustain and have the powerful computers but in spite of that SSS maximize their resources. It was also discussed to process of evolution in transacting in SSS, it said that at past, it has no specific line for every transaction but in present, every transaction has its multiple allotted line and they now use propriety number. It is normal for them cater hundreds to member per day because they cover the whole manila as they are the main office of SSS.

What I liked?

            What I liked is that they prepare and facilitated a simple program to welcome and accommodate us. After the speaker, they open the discussion for questions. Then the questions came out simultaneously until they said that they having fun with us because we are very curious about the details of SSS. They also said that we are smarter than the other batch that they handled. It makes me overwhelmed, because it came from the mouth of the other. It makes a proof that we are one of the top universities on the Philippines. Cheers!

What I didn’t liked?

            Because we consume lots of time on asking questions, we had ended the discussion of late afternoon. The largest printing machine that we originally planned see is cancel because of limited time left on our schedule and in was a rush hour for SSS that time. So we feel sorry for our self of not accomplishing the main propose why we visited SSS. Yes, we are excited to see their technology but the program they had done is great enough for us.

Day 4 (September 13, 2012) at People’s Park in the Sky and Laguna Electronics

            The day four is considered as our relax day where we schedule to go in tourist spot destination, the batch decided two separate the schedule of the two group: big bus and small bus. I belong to the big bus, our schedule is to go to People’s Park in the Sky in Tagaytay. Although, it was not a company and it for pleasure thing we made ourselves enjoy and learn because the technology of PAGASA was settled over there, the Doplar Radar.

What I Learned?

            On this part of our schedule, I learned only some facts. One of those are, former first lady Emelda Marcos who decided to build the Park as their vacation house. And when presented Marcos exploited in malacanang. The government take the house and converted into tourist spot because of it panoramic view as it is in the highest peak of Tagaytay.

What I liked?

            People’s park in the sky is just Jack Ridge here in Davao. What is unique in the people’s park is the 360 degrees of panoramic view that when I saw, I feel like in heaven, I think for a while that how god made this wonderful earth. It was really awesome experience of being there that feels like I am in the top of the world.

            In the afternoon, we visited the company of Laguna Electronics that recently changed their name to Chukkedin to inline in their other international branch. The company manufactured the assembled boards for projectors and other electronics devices. They much like partner of Technology Companies in assembling their products. Companies send their item to Chukkedin, and then Chukkedin is the one assemble the board and send back to the company. The speaker from the Chukkedin presents a video on how the chips are being attached in the board. Only video because there manufacturing area is restricted. And sorry for ourselves. 

              

 Day 5 (September 14, 2012) at J.P. Morgan Chase and Departure from Manila

            In day five, we have visited the J.P. Morgan Chase Company. It was my favorite company because of its unlimited and free drinks for their visitors and employees. The J.P. Morgan Chase is an outsource company that handles transaction from America which comprising Investment Banking, Equity Sales and Research and Trading operations, Treasury and Securities Services, and the Global Corporate Bank. The firm has a number of legal entities operating in the country, including the Manila branch of the bank, which has a commercial banking license as well as a derivatives license, and a securities company with a seat on the Philippine Stock Exchange.

What I Liked?

            What I liked aside their building, unlimited drinks is their communication with other employee. They give value for each other as they are part of diversity. They support it socially, emotionally and spiritually. They also have latest technology, just like the power saving technology that was being implemented all over the building, this help the country for saving energy. I also like what they called the star wars room where they conduct meetings over the network internationally. It was like the thing I saw in the movie where people can meeting using camera and a monitor.

What I didn’t Liked?

            I didn’t like is that J.P. Morgan Chase is monitor by foreign group, there are lots of CCTV at send data outside the country that receive by foreign company to monitor every activity in the Philippines branch. It feels like there was always an eye who is looking on everything you will done. 

Appendix

Recommendations

           I personally recommend to next batch of field trip and seminars of the next year is that choose to go to Manila. It is because there are lot things that makes you inspire to go deeper in our fields of computing. There are lots of company that their strength came from their information technology branch. There also lots of technologies in Manila that we cannot currently seen here in Davao or Mindanao.However, expenses is bigger comparing on having a fieldtrip and seminar locally but it all worthy, sulit na sulit talaga. Just make sure that you booked already your tickets to have the fare discounts.

The topic about the chapter 1 is the system analyst as a project manager. After the topic was delivered, I was able to describe the analyst’s role in a system development project and describe the various types of systems an analyst might work on. I was also learned the concept of an information system, the key role of system analyst in business and the important skills that the analyst must have mush as technical knowledge, good communication to people, and business oriented.

The first subtopic of charter 1 is about of what is an information system. According what is presented, an information system is a collection of interrelated components that collect, process, store, and then provide an output for the information needed to complete a business task. So therefore, information system will be the output provider for the good of the business from the processed data which was collected and stored from an information system. The following are the major types of an information system that the system analyst might work on the future:

· Customer Relationship Management (CRM) – it involves using technology to organize, automate, and synchronize business processes; principally sales activities, but also those for marketing, customer service, and technical support. In short, it is composed of methodologies, software, and usually Internet capabilities that help an enterprise manage customer relationships in an organized way.

· Supply Chain Management (SCM) – it includes product development, product acquisition, manufacturing, and inventory management.

· Accounting and Financial Management (AFM) includes intranet application to maximize employee access to financial data for planning and control.

· Manufacturing Process Management (MPM) – it is the collection of technologies and methods used to define how products are to be manufactured. It is also designed to assist in reducing operational overheads and supporting operational efficiencies in discrete, process, and mixed-mode manufacturing environments.

· Collaboration Support System (CSS) includes integrates order-processing and fulfillment system with SCM, support customer orders (mail, phone, and web).

· Knowledge Management (KM) - comprises a range of strategies and practices used in an organization to identify, create, represent, distribute, and enable adoption of insights and experiences. Such insights and experiences comprise knowledge, either embodied in individuals or embedded in organizations as processes or practices.

The Examples of information system are course registration system, online order system, online banking system and other system that has collect, process, and store activity. Information system can be also other system that uses the Input, Process, Output (IPU) system or deals with inputs, customer support system which includes hardware, software and people, and then produce an output. But here in University of Southeastern Philippines (USEP), examples of an information system are the Student Record Management System (SRMS) for the students and the Human Resource Management System (HRMS) for the employee and faculty of the university, there was also systems for finance and accounting. In the SRMS, it is consist of registrar and database, the registrar is the one who collect, process and store in database the data about the student, then database will provide the output as a the certificate of registration, transcript of records and etc.

But then, why an information system is important for a system analyst? It is because of the following:

· It supports business functions; just like in the SRMS it makes the enrolment easier and more comfortable. It makes the some of the business transactions become faster, less hustle and easy to be done.

· It makes business more competitive, USEP’s SRMS makes the university compete from the other university in terms of what the student experience in enrolment or getting his/her records.

· It enhance productivity and profits, because of SRMS the enrolment process of USEP helps more efficient that can be able to serve the student in a minimum time that means more student will be served at the end of the day.

The second subtopic of the chapter 1 is about on system analysis and system analyst, it tackles of what is system analysis, what the role of system analyst and what is system analyst are doing about. So what is system analysis? It understands the goals and strategies of the business that can be able to help for the success of the business, defining the information requirements that support those goals and strategies this helps to determine on what are the things needed in strategy to accomplish the business goal. Then, what is the system analyst? The system analyst basically is the business problem solver. The system analyst is also the one who investigate, analyzes, design, develop, installs, evaluate, and maintains a company’s information systems. Therefore, a system analyst is a business professional who uses analysis and design techniques to solve business problems using information technology. A system analyst is not all about analyzing the system instead system analyst also do the following:

· Investigation on what is the problem and what are the solutions of the problem.

· Analysis on what is the best and suitable solution of the problem, understanding in details on what a system should accomplish.

· Design and develop of the system that may answer the needs of user and the affected parties, or the application of the solution based on the investigation results. Also specifying in details how components of an information system should be physically implemented.

· Installation of the solution, or deploying the system to the affected parties.

· Evaluation either the solution answer the problem, or not. It is based on the response of the users of the system deployed.

· Maintains the system to support the further need of the user.

The next topic was about the strategic planning. The system analyst must accomplish strategic plans to solve the business problem. The strategic planning is a process during which executives try to answer such question:

· Where the business is now? Or what is the current state of the business, is it productive? These questions determine the strength and weakness of the business. It also helps to develop their strength and compliment their weakness.

· Where they want the business to be? Or what they wanted their business will be after five or ten years? These questions set a goal for the business, and sets business to improve by motivating those goals.

· What they have to do to get there? Or what are the steps they will do to achieve their goals? These questions determine the things that the business should do to reach their goals.

Therefore, strategic planning determines the starting, and finishing points of the business. It also determines the needs and procedure undergo by the business to become better and be able to reach the finishing point.

But what is the role of an analyst in strategic planning? The role of analyst is to develop the information system that supports strategic planning. As stated earlier that the system analyst is the problem solver of the business, this means that the key of strategic plan on a certain business to become successful is depending to a system analyst. System analyst needs to develop an application plan which is a description of the integrated information systems that the organization needs to carry out its business function. This application architecture plan will be the pattern on what must do in accomplishing strategic plans. System analyst also needs to develop a technology architecture plan which is a description of the hardware, software, and communications networks required to implement planned information systems. This technology architecture plan will be the compilation of what are the tools needed in doing the strategic plan.

Strategic plans are used for solving problems of a business. Then, as a rule of system analyst is to solve the business problem. In solving those problems, system analyst must know some steps of approach as follows:

1. Research and understand the problem – in this step, system analyst conduct gathering of data regarding to the problem matters. Then, the data collected will analyze and determine the cause of the problem and think if there is possible way to solve the problem.

2. Verify benefits of solving problem out weight the costs –determine the benefits that can give by aiding the problem. Determine if the cost of solving problem is better than accepting the effect of the problem.

3. Define the requirements for solving the problem – if the cost of aiding the problem is lesser than the cost of accepting the problem, and then identify the things and tools needed to solve the said problem.

4. Develop a set of possible solutions (alternatives) – after determining the requirements for solving the problem, think what possible solution to solve the problem are.

5. Decide which solution is best and recommend – among the solutions identified in the previous step, choose the best solution that will perfectly aid the problem

6. Define the details of the chosen solution – when the best solution was identified, discuss it in more detail things. Determine what are the things needed to accomplish the solution.

7. Implement the solution – in this step, the solution was been applied with a guarantee that that was the solution of the problem.

8. Monitor to ensure desired results – after deploying the solution, it need to be monitor to confirm that it is really the right solution of the problem

It was said that system analyst solves the problem of the business, and businesses address those problem by strategic planning. So what are the usual problems that the system analyst and business wanted to solve. These are typical problems system analysts typically solve.

· Customers want to order product anytime of the day, it was normal situation in a business especially when it is online where the customers able to order anytime they want. But it is hard to difficult for the company to monitor their customers, so to avoid the loss of sales and to serve their customer immediately the aid of a system analysis is needed. Then, what system analyst and business do is improve the Customer Relationship Management and Manufacturing Management.

· Marketing want to know customer needs better. It is difficult to determine the needs of the customers especially on what are their responses on a business function. The business and system analyst usually do is create a forums, and chat rooms.

· Management wants to analyze financial information more efficiently. The management of the business wants to analyze financial information for the transparency. So the system analyst do is to develop the Financial and Accounting Management for easy access to financial information.

· Including to the topic in chapter 1 was as a system analyst was also required traits and skills to them become a real business problem solver. The following traits are those system analysts must have:

· They need to have a computer technology knowledge and programming expertise. As the definition of a system analyst is the one who uses analysis and design techniques to solve business problems using information technology which mean it is essential to a system analyst to have knowledge about the computer technology.

· They can really understand the business problems. How system analyst solves a problem if they did not understand the real problem. Meaning system analyst need to understand the problem first before they can solve the problem.

· They use logical methods for solving problems. To make a reasonable solved problem it need to use logical methods of solving to be able to provide effective proof.

· They have fundamental curiosity. Curiosity is very important for a system analyst because it is the foundation of new ideas. New ideas that could be very useful in solving problems and could be the foundation of another new idea.

· They want to make things better. Creating something is not the end is was just the beginning of another something new. This means that as a system analyst it is not absolutely done in creating new things. Instead, it needs be enhance more better and develop more.

On the other hand, the important knowledge of being a system analyst must have is divided into category as follows; technical knowledge, business knowledge and people knowledge. In terms of skill in was divided into two from the two areas, the hard and soft skills.

The technical knowledge of a system analyst refers to having knowledge about the hardware and software used in computer. Even the system analysis was not focus on programming, but still it is important have knowledge about the technologies especially now at modern days. So as system analyst it is need to know how to use some tools in programming, communication network and connectivity, database management system, and operating systems for more efficient work. That knowledge can be very useful in project planning, systems analysis and design, database and network design, construction, implementation, and support to the system.

The business knowledge refers to the knowledge about the business functions performed by an organization, strategies, plans, traditions, and values of the organization. It also refers to knowledge about the organizational structure, organizational management techniques, and functional work processes. This knowledge helps to a system analyst to analyze more on what are the possible solutions of the business problem because it gives an idea to the system analyst on what are they need and what are they want.

People knowledge refers to the ability to understand on how people think, learn, react to change, communicate, and work. System analyst must predict what are the possible reactions of people on how they adopt on the new environment that will be deploy as an information system. The interpersonal and communication skills of an system analyst are crucial in obtaining the require information from the business and the customer, motivating people to make some changes and aim for the goal, getting cooperation from the people surround because the key of the success of an information system project depends on how the people interact and help the system analyst, and understanding the complexity and workings of an organization in order to provide necessary support.

Hard skills are the skills in technical areas such as database design, programming, and telecommunication which are the necessary skills in doing information system by using the tools of being a technical system analyst. Then, the soft skills are the skills in non-technical areas such as interviewing other people, team management, and leadership. These soft skills are the skill of a system analyst on how they communicate to other people, either to their customer or to their teammates

As a system analyst, they have an access to confidential information about the business, such as salary, an organization’s planned projects, security systems, and so on. Therefore, system analyst must have integrity and ethics like they must keep the any business information in private; they must make plan security in systems that could protect confidential business information because any impropriety can ruin an analyst’s career and reputation.

Being a system analyst, they must be able to make ERP software related, conduct business analysts in different business functions such as auditing, compliance, and security. A system analyst must consider all possible aspect in making an information system.

1. Selection Sort

The algorithm of selection sort finds the minimum value, swaps it with the value in the first position, and repeats these steps for the remainder of the list. The idea of algorithm is quite simple. Array is imaginary divided into parts – sorted and unsorted. At the beginning, sorted part is empty, while unsorted part contains whole array. At every step, algorithm finds minimal element in the unsorted part and adds it to the end of the sorted part. Algorithm stops when unsorted part becomes empty.

2. Insertion Sort

Insertion sort is a simple sorting algorithm that is relatively efficient for small lists and mostly-sorted lists. The algorithm is almost the same with the selection sort. It has two imaginary parts – sorted part that contains the first or the last element of the array, and unsorted contains the rest element. The algorithm is comparing the element of unsorted part into the elements of the sorted part. The element of the unsorted part is placed in the correct position at the sorted part. The algorithm stops when the unsorted part is empty.

3. Bubble Sort

Bubble sort is a simple sorting algorithm. The algorithm starts at the beginning of the data set. It compares the first two elements, and if the first is greater than the second, then it swaps them. It continues doing this for each pair of adjacent elements to the end of the data set. It then starts again with the first two elements, repeating until no swaps have occurred on the last.

4. Shell Sort

Shell sort improves upon bubble sort and insertion sort by moving out of order elements more than one position at a time. One implementation can be described as arranging the data sequence in a two-dimensional array and then sorting the columns of the array using insertion sort.

Empirical Analysis

Algorithm is an effective method expressed as a finite list of well-defined instructions for calculating a function. Then the word “empirical” refers to the information gained by means of observation, experience, or experiment. Therefore, empirical algorithm helps us to analyze the information about the particular algorithm.

There are two branches of empirical algorithm. First is the empirical analysis that deals with the characterization of the behavior of algorithms. Second is the algorithm engineering focuses on empirical methods for improving the performance of algorithms.

Analysis of algorithm

Algorithm analysis is a field of computer science that is dedicated to understand the complexity of algorithm. It also provides theoretical estimates for the resource needed by any algorithm which solves a given computational problem. It helps us to know the efficiency or running time of an algorithm as a function relating the input length to the number of steps or storage location and capacity.

Bog-oh notation

Describe the limiting behavior of a function when the argument tends towards a particular or infinity, usually in terms of simpler function.

Union-Find Algorithm

In computing, given a set of elements, it is often useful to break them up or partition them into a number of separate, non-overlapping sets. A disjoint-set data structure is a data structure that keeps track of such a partitioning. A union-find algorithm is an algorithm that performs two useful operations on such a data structure:

1. Find:Determine which set a particular element is in. Also useful for determining if two elements are in the same set.
2. Union: Combine or merge two sets into a single set.A simple approach to creating a disjoint-set data structure is to create a linked list for each set.

A simple approach to creating a disjoint-set data structure is to create a linked list for each set. The element at the head of each list is chosen as its representative.

MakeSet creates a list of one element. Union appends the two lists, a constant-time operation. The drawback of this implementation is that Find requires Ω(n) or linear time.

This can be avoided by including in each linked list node a pointer to the head of the list; then Find takes constant time. However, Union now has to update each element of the list being appended to make it point to the head of the new combined list, requiring Ω(n) time.

Disjoint-set data structures model the partitioning of a set, for example to keep track of the connected components of an undirected graph. This model can then be used to determine whether two vertices belong to the same component, or whether adding an edge between them would result in a cycle.
