Hello,
axolotl v1.8 has been released.
https://github.com/louism33/Axolotl
The main changes are bugfixes, but these have made the engine a bit stronger than before. I roughly estimate the elo rating to be about 2400, and I would be grateful to anyone who can give me a more precise number.
The code is open source of course, and I am thankful to anyone who has a look, or benefits from axolotl in any way.
I have a couple of issues I would love some help with:
1. On the STS suite, the weakest challenges by far are King Safety (number 11) and Centre Control (number 12), where the engine performs pretty badly. I am not really sure how to improve at this, beyond trial and error, as my engine is a better chess player than I am.
2. In a "go movetime 10000" from startpos, my engine registers about 250,000 nps (and takes a while to get to this speed). On my machine, stockfish gets 1,250,000 for the same command. My engine is written in Java, so I am not expecting parity, but I think doubling my nps to 500,000 is not overly ambitious. Any feedback on this goal, or help achieving it, is hugely appreciated. (For the record, startpos "perft 7" gives us 60,000,000 nps, with bulk counting, while stockfish gets 166,000,000 on perft 7)
Thanks in advance for any feedback, and if you can give me any ideas about how to make progress, I would be hugely grateful
Louis
