Description

from Mark Uniacke's report on the 4th Computer Olympiad 1992 :

Search techniques used are minimal-window, alpha-beta with extensions for check evasion, recaptures, singular moves and promotions. Move ordering is by history heuristic, refutation and transposition-table moves and captures. Positional values may range up to +/- 1 Pawn. Development time is 2 years on a very part time basis.
