This website is my personal effort to help the programming contest entusiasts around the world. I developed it in 2001 as a guide to myself and the ACM-ICPC contestants, it was then called the ACMSolver.org. It has been noted as an ICPC blog in the Wikipedia: The ACM-ICPC. A little background: I have worked as a programming contest problem setter for the University de Valladolid (UVa) Online Judge in 2001 (see problem numbers: 10219, 10220, 10221, 10222, also organised (contest director) a national computer programming contest in Bangladesh in 2007 (see DIPC07 contest). I have compiled and produced a programming contest study material in 2006 titled the Art of Programming Contest, which is cited in an article published by Dr. Dobbs Journal and also in the supporting materials of the Wikivarsity book Design and Analysis of Algorithms as well as in the ACM UVa Online judge (Read more). I plan to produce a revised version of the book soon. I also worked as a coach for the University of Newcastle's ACM-ICPC teams and led them to USyd's South Pacific Programming contest in 2013.
