This site currently includes about 5,200 olympiad problems and about 1,700 other problems. I have given solutions for about 2,700 Olympiad problems (and almost all the Putnam and AIME problems). My ultimate objective is to include a wide variety of interesting problems of all levels of difficulty. In general, I have no interest in pure bookwork problems.
If anyone wants to supply solutions, I am particularly interested in the missing solutions to the Iberoamerican olympiad.
Two features about the site are unusual. The first is that I strive for completeness. There are often many sites that give the last few years' problems for an olympiad, but this is usually the only site that gives all the problems. The second is that I try to put up solutions. Inevitably solutions will lag the problems, maybe by years!
I am currently trying to collect the Polish olympiad problems (last round, highest level as usual). So far I have only found 1982 onwards. The olympiad seems to go back to 1950. Any help in getting the missing problems would be much appreciated.
I am also trying to collect the Spanish olympiad problems (last round). So far I have only found 1990 onwards. Any help with earlier years would be appreciated. Spanish language would be fine.
I am also interested in collecting the Indian National Olympiad (INMO). I believe it started in 1986. I am missing 1986-1994.
Finally, I am interested in the Argentine olympiad (tercer nivel). I have found 1995-2003, but it started in 1984. Does anyone have any of 1984-1994? Spanish is ok, although I would prefer English.
Corrections etc are always welcome! Help in finding missing problems is also most welcome. I have no special access to question papers, so copies of the latest olympiads are always welcome, if they are not yet on the site.
