Competitive Programming
Competitive programming is a mind sport usually held over the Internet or a local network, involving participants trying to program according to provided specifications. Contestants are referred to as ''sport programmers''. Competitive programming is recognized and supported by several multinational software and Internet companies, such as Google and Facebook. A programming competition generally involves the host presenting a set of logical or mathematical problems, also known as puzzles, to the contestants (who can vary in number from tens or even hundreds to several thousands), and contestants are required to write computer programs capable of solving each problem. Judging is based mostly upon number of problems solved and time spent for writing successful solutions, but may also include other factors (quality of output produced, execution time, memory usage, program size, etc.) History One of the oldest contests known is the International Collegiate Programming Contest (I ...

Daniel Sleator
Daniel Dominic Kaplan Sleator (born 10 December 1953) is a Professor of Computer Science at Carnegie Mellon University, Pittsburgh, United States. In 1999, he won the ACM Paris Kanellakis Award (jointly with Robert Tarjan) for the splay tree data structure. He was one of the pioneers in amortized analysis of algorithms, early examples of which were the analyses of the move-to-front heuristic, and splay trees. He invented many data structures with Robert Tarjan, such as splay trees, link/cut trees, and skew heaps. The Sleator and Tarjan paper on the move-to-front heuristic first suggested the idea of comparing an online algorithm to an optimal offline algorithm, for which the term competitive analysis was later coined in a paper of Karlin, Manasse, Rudolph, and Sleator. Sleator also developed the theory of link grammars, and the Serioso music analyzer for analyzing meter and harmony in written music. Personal life Sleator was born to William Warner Sleator, Jr., a profess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UVa Online Judge
UVa Online Judge is an online automated judge for programming problems hosted by University of Valladolid. Its problem archive has over 4300 problems and user registration is open to everyone. There are currently over 100000 registered users. A user may submit a solution in ANSI C (C89), C++ (C++98), Pascal, Java, C++11 or Python. Originally it began without the last three options, but the Java option was added in 2001, the C++11 option was added in 2014, then the Python option was added in 2016. UVa OJ also hosts contests. In the contest environment the user has a limited time to solve a small set of problems History The UVa OJ was created in 1995 by Miguel Ángel Revilla, a mathematician teaching algorithms at the University of Valladolid in Spain. Ciriaco García de Celis, an informatics student at the University of Valladolid, implemented the first version of the judge using Bash, and then developed and maintained it for more than eight years. In April 1997, the judge b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPOJ
SPOJ (Sphere Online Judge) is an online judge system with over 315,000 registered users and over 20,000 problems. Tasks are prepared by its community of problem setters or are taken from previous programming contests. SPOJ allows advanced users to organize contests under their own rules and also includes a forum where programmers can discuss how to solve a particular problem. Apart from the English language, SPOJ also offers its content in Polish, Portuguese and Vietnamese languages. The solution to problems can be submitted in over 40 programming languages, including esoteric ones, via the Sphere Engine. It is run by the Polish company Sphere Research Labs. The website is considered both an automated evaluator of user-submitted programs as well as an online learning platform to help people understand and solve computational tasks. It also allows students to compare paradigms and approaches with a wide variety of languages. History This system was originally created to apply ...

International Collegiate Programming Contest
The ICPC International Collegiate Programming Contest, known as the ICPC, is an annual multi-tiered competitive programming competition among the universities of the world. Directed by ICPC Executive Director and Baylor Professor Dr. William B. Poucher, the ICPC operates autonomous regional contests covering six continents culminating in a global World Finals every year. In 2018, ICPC participation included 52,709 students from 3,233 universities in 110 countries. The ICPC operates under the auspices of the ICPC Foundation and operates under agreements with host universities and non-profits, all in accordance with the ICPC Policies and Procedures. From 1977 until 2017 ICPC was held under the auspices of ACM and was referred to as ACM-ICPC. Mission The ICPC, the “International Collegiate Programming Contest”, is an extra-curricular, competitive programming sport for students at universities around the world.

HackerRank
HackerRank is a technology company that focuses on competitive programming challenges for both consumers and businesses. Developers compete by writing programs according to provided specifications. HackerRank's programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, JavaScript) and span multiple computer science domains. HackerRank categorizes most of their programming challenges into a number of core computer science domains, including the management of databases, mathematics, artificial intelligence, among other subjects. When a programmer submits a solution to a programming challenge, their submission is scored on the accuracy of their output. Programmers are then ranked globally on the HackerRank leaderboard and earn badges based on their accomplishments, which is intended to drive competition among users. In addition to individual coding challenges, HackerRank also hosts contests (often referred to by HackerRank as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Google Code Jam
Google Code Jam is an international programming competition hosted and administered by Google. The competition began in 2003.
