### Ziggy - v0.7 | |
### | |
Description | |
=========== | |
Yet another chess engine. Created with a *little* help and inspiration from other chess engines | |
such as CPW, Mediocre, TSCP, Glaurung, Stockfish, Fruit, and inspirations and guides from people | |
like Fritz Reul (Loop) and Ed Schröder (Rebel). | |
To be done | |
========== | |
# C++'d - I guess. :( | |
! Search extensions. | |
! Fix memory issues. | |
! Deterministic mode. | |
! Some actual parsing of UCI's options. | |
# Better transposition entries. | |
# Better transposition table (with generations, clusters of entries, etc) | |
# Only generate 'good captures' in quiescence. | |
# Dynamic R value in Null-Moves. | |
! Killer moves | |
? Contempt factor | |
# Endgame tablebases. | |
! Evaluation. :( | |
Usage instructions | |
================== | |
UCI mode: | |
java -jar ziggy.jar | |
Benchmark mode: | |
java -jar ziggy.jar <bench> <type=perft | depth | suite> <file=suite/fen file> | |
[time=time for each position (s)] [depth=fixed depth for each position] | |
Both modes: | |
In both UCI and benchmark mode there are a number of settings which can be adjusted | |
as requested. | |
Setting Default Description | |
--------------------------------- -------- ----------------------------------------------------- | |
mc=<on | off> on Turns Multi-Cut (MC) on or off. | |
mc_cutoffs=int 3 Sets MCs C param. | |
mc_expand=int 10 Sets MCs E param. | |
mc_reduction=int 2 Sets MCs R param. | |
mc_piece=<on | off> off Turns MCs piece-check on or off. | |
mc_reorder=<on | off> off Turns MCs reordering of cut nodes on or off. | |
mc_usetrans=<on | off> off Will use the transposition table with MC. | |
mc_apply=<cut | trans | or> trans Where to apply MC: | |
- cut: At expected cut nodes. | |
- trans: When a shallower search indicates fail-high. | |
- or: If either condition holds. | |
nm=<on | off> on Turns NMs pruning on or off. | |
nm_reduction=int 2 Sets NMs R param. | |
lmr=<on | off> on Turns LMR on or off. | |
lmr_fdm=int 4 Sets the no. of full depth moves in LMR. | |
asp=int 50 Sets the size of the aspiration window. | |
Examples: | |
java -jar ziggy.jar bench type=suite file=wac.txt time=10 | |
-- Will run the test-suite Win At Chess, with a time constraints of 10 seconds per position. | |
java -jar ziggy.jar bench type=suite file=wac.txt depth=7 | |
-- Same, but with a fixed depth of 7 instead of time constraints. | |
java -jar ziggy.jar bench type=suite file=wac.txt depth=7 lmr=off nm=off mc=off | |
-- Same, but without LMR, NM- and MC pruning. |
