Tin Woodman [1]

Tinman,
a didactic open source chess engine by Michael Leany, written in Rust, compliant to the Chess Engine Communication Protocol. Tinman is licensed under the Mozilla Public License, V. 2.0, and was first released in January 2020 [2].

Description

So far, Tinman is quite rudimentary and lacks state of the art search techniques and evaluation terms - and has therefore huge potential to improve further. It represents the board with a little-endian file-rank mapped bitboard definition, and applies Hyperbola Quintessence to determine sliding piece attacks [3]. Search is plain alpha-beta with transposition table, check extension and quiescence inside the iterative deepening loop [4], considering material and piece-square tables as evaluation terms at the leaves [5].
