https://github.com/Adam-Kulju/Patricia/releases/tag/5Leider hier nur eine avx2 Binary (v3.exe runterladen) für Windoofs. Ich habe aber Jim Ablett auf talkchess schon eine PM geschrieben und hoffe auf zeitnahe JA-binaries, dann auch avx512, Android etc. Daher schiebe ich meinen Patricia 5 Testrun noch etwas auf.
Ich habe einen Download für TBG gemacht, der die ArenaGUI mit Patricia 5 enthält. Spielbereit (Skill 20) vorinstalliert, plus kleines Eröffnungsbuch.
Skill ändern: STRG+1,Bedenkzeit ändern: STRG+L
Ich habe für Patricia 4 Threads und 1 GB Hash voreingestellt und eine flotte Blitzstufe voreingestellt (der Mensch kann solange überlegen wie er will). Für das Spiel gegen Menschen auf fast allen halbwegs modernen PCs geeignet...

Sorry about the wait; I had hoped to train a new set of networks before releasing Patricia 5.0, but couldn't wait any longer.
+70 elo LTC
+60k EAS
Tablebase support
Improved (and incredibly aggressive) human mode - check it out!
The main feature added was switching to an evaluation involving 3 separate neural networks with different aggression/strength tradeoffs, which increased aggression overall without sacrificing strength. Patricia swaps between them based on aspects of the position such as material and evaluation - e.g. when in a winning middlegame, use the most aggressive net to search for a knockout blow.
Many search features were added as well, though after little progress these last two months I don't remember them well enough to make a comprehensive list.
It's been a joy to watch Patricia play some incredible games at CCC and TCEC - she's been able to spring unexpected winning sacrifices on top engines such as Torch a few times which is quite the achievement.
The metric that Patricia's aggression claims are based off of is Stefan Pohl's EAS tool, which is the most well known and best regarded tool for determining the aggressiveness of chess engines. It looks at a combination of factors, such as sacrifice rate, short win rate, and unnecessary draw rate, and outputs a score that captures how "exciting" an engine tends to play. It's not a perfect statistic but from my experience it reflects the "eye test" well.
The average engine's EAS score generally falls between 50,000 and 100,000. The most aggressive top engine is Stockfish, due to its extreme tactical ability; it has an EAS score of 190,000.
By contrast, Patricia's EAS score is 430,000 as tested by Pohl himself.
It's worth noting that Patricia is still extremely powerful, clocking in at 3500 on the CCRL Blitz rating list; she can put up a solid fight against top engines, and will crush any humans.
