This is the first release of byte-knight. Based on play against stash, the estimated ELO of byte-knight is around ~1800. The following features are implemented in this version:
Search
- Iterative deepening
- Negamax with a/b pruning
- Quiescent search
- Move ordering using basic MVV/LVA table
- PeSTO based evaluation with tapering using the PeSTO PSQT values
- Transposition table (used for move ordering and cutoffs)
Game
I've written my own board representation complete with legal and pseudo-legal move generation as well as magic bitboards for sliding piece attacks. Performance is acceptable and will likely be improved on in the future.
These release notes are auto-generated by Github.
