Re: new axolotl

Hi Necromancer, Thank you so much for taking the time! And thank you also for your really good ideas. How would you go about evaluating your King Safety and Passed Pawn eval? At the moment I mainly use the Strategic test suite, and some Texel Tuning. Many thanks again, and I will post some more prec...

Re: new axolotl

Hi Necromancer, thanks for the quick reply. Yes, unfortunately you will need at least Java 11 to run axolotl, which is easily available online : https://openjdk.java.net/projects/jdk/11/ or https://www.oracle.com/technetwork/java/javase/downloads/jdk11-downloads-5066655.html I ran the STS suite at 5...

new axolotl

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 i...

Searching crazy positions

Hello, When my engine searches from the starting position, I noticed that it considers board positions which are completely terrible, such as rnb1k1nr/pppp1ppp/8/2K5/4q3/8/PPP3PP/RNBQ1B1R b kq - 1 15 or rnbq2nr/pppp2pp/5k2/8/1b2P3/2N5/PPP2PPP/R1BQKBNR w KQ - 0 1 these are searched at a depth of 11, ...

Max Threads / Hash size

Hi all, how do engines decide what the maximum number of allowed threads should be? I am limited to a 4 core machine, and using a large number of threads does not improve playing strength, and I do not know what would happen if my engine was run on something powerful. Same with hash sizes. So the qu...

Side question: should the depth we send in info string should be the iterative deepening depth, or should we also ...

UCI flexibility

Hello, I have just implemented a Pawn Hash Table, and it has raised some questions about how rigourously we must follow the UCI spec. 1. If you set the TT size in my Engine to something small like 1mb, I will still always use a 1mb pawn hash table size. Is this a problem? Should I make the pawn size...
