Re: TOSHIBA LTC CHESS ENGINE TOURNAMENT
Hello folks, introducing Soon to join competition: engine SFT 230127-f0a0b-d3860-master (Rebalance usage of history heuristics in pruning).
This is a copy of a test version of stockfish, as tested on stockfish servers,on jan 27, 2023. It is a nice improvement upon master “d3860-master (Rebalance usage of history heuristics in pruning).
The executables come in multiple architecture (arch) versions: modern, popcnt, bmi, bmi2, vnni, avx, avxnni, avx2, avx256, avs512, arm7, arm7-neon, arm8, arm64_apple-silicon, riscv64. And some include an optimized version for the intel i3 (Profile Guide Optimized, PGO).
pgo versionS, also included, are optimized for an intel i3 processor. It should be playable in just about every popular processor platform compatible with intel processors, as long as it is a 64 bit system.
Compiled by g++ (GNUC) 12.2.0 on MinGW64
Compilation settings include: 64bit SSE41 SSSE3 SSE2 POPCNT
__VERSION__ macro expands to: 12.2.0
BENCH MESSAGE: (running the engine in command prompt with the ´bench´command.)
SFT 230127-f0a0b-d3860 reduction_killer_3b, Only for main killers, but with reduced history condition, Bench: 4069938, XInTheDark committed Jan 27, 2023. 1 parent 5fa8830 commit f0a0b7c1. Elo gain: 2.22 [0.61,3.80] (95%). By the Stockfish developers (see AUTHORS file)
SPEED TEST (on Intel i3, 2.20 GHZ)
Total time (ms) : 17425
Nodes searched : 4069938
Nodes/second : 233568
IMPORTANT MEANING OF ALL THIS STUFF
ELO POINTS GAIN OVER ITS MASTER: 2.22 [0.61,3.80] (95%)
MASTER: d3860-master (Rebalance usage of history heuristics in pruning).

Improve excluded move logic
PR consists of 2 improvements on nodes with excludeMove:
1. Remove xoring the posKey with make_key(excludedMove)
Since we never call tte->save anymore with excludedMove,
the unique left purpose of the xoring was to avoid a TT hit.
Nevertheless on a normal bench run this produced ~25 false positives
(key collisions)
To avoid that we now forbid early TT cutoff's with excludeMove
Maybe these accesses to TT with xored key caused useless misses
in the CPU caches (L1, L2 ...)
Now doing the probe with the same key as the enclosing search does,
should hit the CPU cache.
2. Don't probe Tablebases with excludedMove.
This can't be tested on fishtest, but it's obvious that
tablebases don't deliver any information about suboptimal moves.
Side note:
Very surprisingly it looks like we cannot use static eval's from
TT since they slightly differ over time due to changing optimism.
Attempts to use static eval's from TT did loose about 13 ELO.
This is something about to investigate.
