Monolith 1.0
Posted: Thu Oct 18, 2018 1:22 pm
I'm very proud to finally release Monolith 1.0 after almost 2 years of delights and frustration.
The engine is certainly nothing ground breaking but simply a plain old alpha-beta-searcher like hundreds of its kind,
but writing it has enriched those past 2 years immensely. To every non-programmer out there:
If you want to broaden your horizon and learn a programming language, there's no better way to get started than to
write a chess engine. Yes, it demands a great lot of time, but I regret no single hour of it.
Source and binaries can be found here: https://github.com/cimarronOST/Monolith/releases
Main changes to version 0.4:
-added support for multi-processors with simplified-ABDADA
-added support for syzygy endgame-tablebases
-added support for PEXT instruction
-added new search enhancements (SEE pruning, singular extension, LMR, aspiration window)
-added new evaluation terms
-tuned the evaluation automatically with Texel's tuning method
-simplified the code
-fixed a bug that caused crashes while moving backwards through the game
Strength estimate (bullet games):
Score of Monolith 1.0 vs Monolith 0.4: 6481 - 1470 - 2049 [0.751] 10000
Elo difference: 191.36 +/- 6.70
I'll also add Android compiles soon. A pity I'm always a couple of days too late with my releases for Graham's ongoing Division tourneys,
but I'm looking forward to the next series.
Have fun, that's what it's all about.
