Zweistein: A Dynamic Programming Evaluation Function for Einstein W"urfelt Nicht!

This paper introduces Zweistein, a dynamic programming evaluation function for Einstein W"urfelt Nicht! (EWN). Instead of relying on human knowledge to craft an evaluation function, Zweistein uses a data-centric approach that eliminates the need for parameter tuning. The idea is to use a vector recording the distance to the corner of all pieces. This distance vector captures the essence of EWN. It not only outperforms many traditional EWN evaluation functions but also won first place in the TCGA 2023 competition.
