There have been no detected repetitions of the compositions generated to date." It is not programmed or told what sort of compositions to create (beyond being of the #3 variety, at this point). "Chesthetica neither takes these constructs from actual games nor extrapolates them from endgame tablebases (which are currently limited to seven pieces, I believe). In the ChessBase article announcing the work, he says: The problems are completely synthesized from only some rough inputs, the way most problems are composed by composition masters. The result is a large body of interesting chess problems found by a computer, moderated by humans, and arranged by difficult level.Īzlan Iqbal (PhD) has programmed a chess problem generator. Flawed problems are identified in comments and are disabled by the site administrator. The easy problems are quickly given a low difficulty rating and are not shown to high rated players. simple captures with no strategy involved) or flawed in some way (due to the chess engine not seeing some detail of the position). Many of the problems turn out to be uninteresting (e.g. Each problem is also given an ELO-like rating based on which users solved or failed to solve the problem. The users can also comment on the problems, tag them and rate how they liked the problem. These positions are then offered to users of the site who try to find the computer's selected best move. Specifically it looks for positions in which one side has a way to win material within a few moves, but where alternative moves do not. It looks for interesting positions that can be presented as chess problems. ChessTempo uses a chess engine to analyze positions from a large database of master games.
