High Quality Content by WIKIPEDIA articles! Project Euler is a website dedicated to a series of math problems intended to be solved with computer programs. The project attracts adults and students interested in mathematics and computer programming. As of 23 March 2010 (2010 -03-23)[update], it included 283 problems of varying difficulty, each solvable in less than a minute using an efficient algorithm on a modestly powered computer. New questions have been periodically added since the project's creation in 2001. A forum specific to each question may be perused after the user has correctly answered the given question. Accessible to logged-in users is a high scorers section that ranks users by the number of problems solved. Six different scoring levels are defined (level 1 - 5 are denoted by platonic solids and level 6 is denoted by sphere), plus a special Eulerians level that contains the members who have solved at least half of the most recent 25 problems.
