Phoenix Plant Sculpture [1]

an UCI compliant Java chess engine and masters thesis program by Rahul Aralikatte, which is basically a modified CuckooChess by Peter Österlund. Ten piece-square tables, for all six piece types of the opening phase, plus four piece types (no rook and queen) of the endgame, that is a vector of 640 values is interpreted as chromosome to be trained by a genetic algorithm approach. After 1000 games [2], the modified engine Phoenix apparently outperformed its parent CuckooChess with a rating of 2546 (an increase of 19 points) [3]. After investigations by the original CuckooChess author, he found Phoenix played all games with White! Further, by using the published piece-square tables, Peter Österlund found the modified version around 400 elo weaker than the original, assuming Hanlon's razor applied [4].
