Arimaa Computer Championship Challenge 2004
The first Arimaa Challenge match was won by the human player Omar Syed with 8-0 against the program Bomb of David Fotland. (see press release).background
Arimaa is a new chess-like strategic board game invented by Omar and Aamir Syed. The game differs from chess in (among others) the following two ways.- A variable opening position: players are free to choose the place of the pieces within the first two rows of the board.
- Complex moves: each move consists of 4 piece-movements that not only include shifts or captures, but also pulling, pushing and immobilization of opponent pieces.
In order to stimulate AI-research, the inventors of Arimaa called out the Arimaa Challenge: to the first person, company or organization that builds a program that defeats a chosen human Arimaa player in an official Arimaa challenge match before 2020, a prize of $ 10.000 USD will be awarded.
Each year a match will be organized. The match consists of two parts: first a selection match will be played between computer programs to select the best computer program, then the best program plays a match against a chosen human Arimaa player. The first challenge took place in January and February 2004 in co-operation with ICGA. ICGA oversaw the selection of the best program and the challenge match.
