Celes

Home * Engines * Celes

Celes, (31337) a chess engine by Johan Hutting, at times supported by Marcel Veldhuizen, written in Delphi compliant to the Chess Engine Communication Protocol , and since version 0.70 the UCI protocol. Celes was initially called 31337, but that's not a valid ICC and/or FICS name, so Celes was used. It applies alpha-beta inside an iterative deepening framework with aspiration windows, further using the killer and null-move heuristic. Celes utilizes a main transposition table, a separate opening book transposition table, which covers transpositions of opening lines, and caches its evaluation results due to a evaluation hash table and pawn hash table.

=Tournament Play= 31337/Celes played three CSVN tournaments over the board, the ICT 2001, DOCCC 2002 and the ICT 2003, as well as four CCT Tournaments, CCT3, CCT4, CCT5 and CCT6.
