Monolith 3 first update in 6 years. What's new?
A lot of small improvements everywhere, the biggest strength gains came from adding history correction and tuning the search parameters with SPSA with the help of weather-factory.
More importantly, Monolith 3 is a much more stable engine than Monolith 2 after having fixed a series of bugs that were unraveled after switching testing from Windows to Linux, summarized here.
Monolith is still old-school and has not adapted NNUE.
Strength gain estimate at short time control:
Score of Monolith 3 vs Monolith 2: 6704 - 230 - 3066 [0.824] 10000
Elo difference: 267.8 +/- 6.1
