Chess engine: Leorik 1.0 (for Windows, Linux and Mac)


Leorik - UCI chess engine
This version combines a pretty fast move generator, copy&make and incremental updates of the Zobrist key and the PST based evaluation to search several million nodes per second. But the search does not implement any unsafe pruning techniques or reductions and so it suffers from a high branching factor and remains quite shallow even at higher time controls. This lack of sophistication in both it's search and it's evaluation causes this version to play rather weak at an estimated 2150 ELO.
