Scorpio 2.5 (WB)
C++ source; Win32/64 & Linux 32/64; mp; own endgame bitbases
this is a source-code-only update
- smooth scaling null move
- a bit aggressive reduction and pruning
- a bug in root move ordering fixed (x86-64 version only)
- Some eval changes but I plan to tune it in the future using cutechess-cli's GA tuner (fingers crossed) ;)
- Cluster tested so i expect a few elos up. But I will wait and see what happens because i didnt test at longer TC
- few speed optimizations but I am beginning to understand some part of scorpio needs some serious optimization
- failed attempt on singular extensions...will be revised in the next version
