Re: Seer

I played a few test games now in the CuteChessGUI on my old quadcore and actually it really uses always one extra thread(core), even when it is not its turn? Oh. Crap. You're totally right. I added some code to fix this behavior, but it somehow didn't make its way to GitHub... I'll fix this soon. T...

Re: delete informant symbols before a given move or ply nr in big pgn database

There are no informant symbols anymore in the example? I don't want al informant symbols to be removed. Only before a given move or ply number. Oh, I thought it's about the '?' and '!' in the game part itself. Then I don't understand what exactly you want to be removed. In the example game I posted...

... I played a few test games now in the CuteChessGUI on my old quadcore and actually it really uses always one extra thread(core), even when it is not its turn? It plays very interesting chess, which looks very much like 'young' Leela(LC0), also with all its strengths and weaknesses. I like it :) ...

Re: Seer

Thanks! I will try it out today. I am not very optimistic though, because the core2 binary you released now, just adds around 4% in speed. Obviously missing popcount and/or newer instructions makes a huge difference here (note that this hardware is from 2009). For better comparison, vanilla SF12 (n...

Re: Seer

... Thanks for the binaries. I still would like to create a core2 compile (if you have time for a makefile instead of cmake), may be I can squeeze a bit more out of Seer for my old quadcore. What flags are used for the generic one currently? ... Sure. I can add a core2 compile in a little bit. For ...

Re: Seer

I traced the issue with loading the Weights on Windows to Windows interpreting bytes equaling 26 as indicating the end of the file. I've now added binaries to the release page for version 1.0 and appended the version number to the engine's name. Binaries can now be found here: https://github.com/co...

Re: Seer

... Again the appeal to engine authors - please create a separate thread if introducing a new engine or important updates. The new engines 2020 thread is intended for testers. It would be interesting to see whether AMD's PEXT beats the native C PEXT implementation, most use magic bitboards as fallb...
