Version 1.0
Chess engine based on min-max algorithm, iterative deepening and transposition tables.
- Player vs AI
- AI vs AI
- AI vs FICS (Free Internet Chess Server)
- negamax search - simple implementation of minmax algorithm
- alpha-beta pruning - decreases the number of nodes parsed by the negamax
- transposition tables - cache for parsed positions, prevents from double calculation of node
- iterative deepening - iterative increasing of maximal depth
- quiescence search - prevents from horizon problem, calculates very deep nodes (only captures, promotions or checks)
- Zobrist hashing - calculates unique number for the board
Proxima b is playing on Free Internet Chess Server (FICS) as "proximab(C)". Feel free to play with him :) The most common setting for games is 15/0 (or 10/0).
