Problems from OlympiadsAt this moment the archive contains 9309 problems.
How you can helpAny help is most welcome. This may include problems, solutions, and/or feedback about certain competitions. If you want to provide problems, we are particularly interested in those on a dark background. We are generally very happy to receive national contests that are not yet offered on the site (such as those in other countries), although it may be a good idea to contact us first - some such contests are already waiting in a stack. The materials you send us should be in one of the following forms (in the order of preference):
Your help will be duly acknowledged, and your contribution will probably appear on the site in as soon as one week! One more thing: Statistically, in such a large set of problems some mistakes must occur. We try to reduce their number to a minimum. If you encounter any (for example, a senseless or wrong problem, a language mistake, a typo, etc.), please report it by writing us, and we‘ll correct it as soon as possible. Thanks to the following people for reporting mistakes: Babis Stergiou, Do Hoang Giang, Ercole Suppa, Francesco Morandin, Hae In Lee, Harun �iljak, Juergen Voigt, Krzysztof Gogolews, Liu Guocan, Matti Lehtinen, Phan Anh Do, Philipp D�rsek, Shayan Dashmiz, and Yair Mulian. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
