Re: Did anyone write a xiangqi chess engine?

Shogi is next. You get to drop pieces out of your hand onto the board during the game, not just for promotion.

Re: Any recent examples of strong programs losing with white at longer time controls?

Are there are any games to check out? It would be fun to go through them to see what happened. Of course, it shouldn't be a purposefully bad opening. For the current TCEC contest, not including the superfinal games, there were 88 wins for black. I:\pgn\tcec\seasons\20>type general.dat Games : 661 (...

Re: Did anyone write a xiangqi chess engine?

On github there are 166 Javascript chinese chess projects (probably more, I only captured the ones that used terms Chinese chess)
https://github.com/search?q=chinese+chess
I guess some of those projects may have helpful positional tests.

Re: Andscacs nnue 0.1

Daniel and Engin could use SF NNUE if instead of integrating Daniel Shawul's GPL code into their engine they would use his dll. This has happened before, e.g. GUIs (code closed) accessing bitbase dll. You can use the dll and distribute the source code for it and you comply with the GPL and your eng...

Re: +100 elo breakthrough in new rewritten Lco engine ( Ceres)

There is nothing wrong with the LC0 team waiting until they feel comfortable before making a release. If we get our bun in a knot because we want it now, we can always pull the source and build it ourselves. It is like the SF official releases. There are long, long waits between new OFFICIAL version...

Re: correspondence chess in the age of NNUE

It takes a very long time for a correspondence tournament to complete.
I guess in about 8 more months we will see outcomes from using NNUE stuff to analyze

It also has a separate "wood count", but you can put it in the PST by simply adding the piece value to every square of the corresponding PST. The only other element in PeSTO is a Tempo bonus.
That is astounding. You must have a very good search.

Re: Evaluation reflections

I agree with Sven, Using PST as only chess knowledge helped me to focus on getting a solid search engine first. After adding more chess knowledge the search parameters stayed pretty much the same, and changing them always led to worse play. The only changes I made to the search parameters concerned...

Re: Evaluation reflections

If you would like to see a really simple evaluation that is effective, look at Olithink. The whole program is about 50K and this list: http://ccrl.chessdom.com/ccrl/4040/ has it ranked above programs like Nimzo and Yace. The main ingredient of the Olithink evaluation is mobility, a term that I think...

Re: Stockfish hangs

Perhaps I should simply refrain from sending 'ucinewgame'? Since there was no earlier game, this seems to comply even with the newer specs. I am not sure if they are compliant or not, but there are some engines that must have either the position setup or ucinewgame or they will not have the startin...
