Purple Haze,
a free open source chess engine by Vincent Ollivier compliant to the Chess Engine Communication Protocol and distributed under the terms of the GNU General Public License version 3 [2].
Purple Haze uses some features of C++11, so one needs GCC >= 4.6 or Clang >= 3.0 [3] to compile it.
Contents
Description
Board Representation
Purple Haze has a 0x88 board representation combined with piece-lists, and utilizes two arrays indexed by 0x88 square relations, containing either direction and boolean information in std::bitset<7> whether a piece type may attack a square [4], both used for lazy or staged move generation concerning legality of hash move and killers.
Search
The PVS implementation [5] uses node type as template parameter, and applies adaptive null move pruning, extended futility pruning, and LMR etc. [6] inside its iterative deepening framework with transposition table.
Evaluation
The evaluation features a material hash table and tapers between opening and endgame piece-square tables [7].
