Performance comparison between selected chess engines

Abstract

Selected chess engines were compared to each other in terms of performance, using Lucas Chess. The list of engines was cut into three categories, depending on strength in ELO points. The point of this study is to find the strongest and the lightest engines in each category. Then, each category was tested using three different starting positions. White, black and overall wins were highlighted. At the same time, data of CPU and RAM usage of each engine was collected. A script was developed to print CPU and RAM usage of a specific process. Maximum and average percent of used CPU thread and RAM were highlighted. Chess engines with most amount of wins were, from weakest to strongest: Bikjump, Rybka and Stockfish. Least amount of system resources was consumed by: Cinnamon, Demolito and Critter.
