Re: When will the chess programmers write an engine that plans ?

Look ahead with millions of NPS is not planning for me. It is also not knowledge for me. A plan needs no search depth of 30-40. It needs no AB search at all. A plan is a concept. Where to manoeuvre the pieces and WHY to do so. A plan is a thesis. And the search tree could find out if the thesis Wor...

Re: When will the chess programmers write an engine that plans ?

At some point, computers will see 100 plies ahead. No matter how you look at it, that's strategic. It's not strategy or tactics. It's calculation. Both strategy and tactics are calculation. For computers, there is no strategy or tactics. It's just calculation. Strategy and tactics are meaningful co...

Re: Scorpio 3.0.7 NN 42850

Hi Werner, Thanks for the test. I just wanted to be sure T40 nets work with INT8. The default network with medium Ender is used for CCCC. @Steppenwolf, the installation is pretty easy. All you have to do is download the install script for windows (install.bat) or for linux (install.sh). Run that to ...

Re: Scorpio 3.0.7 NN 42850

Hi Werner, What changes did you make? My guess is a fresh install was needed instead of editing scorpio.ini. Anyway, I am glad that T40 nets work with INT8 now -- there was some major bug with INT8 calibration using EPD files. My tests show that Scorpio with T40 net is slightly weaker than with Lc0 ...

Re: Engines playing Musketeer Chess, good price

Isn't losing the gating piece when king is in check already punishment enough? It would be simpler to just allow gating every time the piece in front moves, and then let the consequences (e.g. gating piece being immediately captured being one of them) prevail. If the king is incheck, obviously the g...

Re: Engines playing Musketeer Chess, good price

For the record, nebiyu misses this rule too. e9f9 is a bad move but I don't see why it is not allowed? Gating always occurs the first time the piece in front moves, right? The idea is something similar to castling rights where if the king is under attack and is forced to move, it loses the right to ...

Re: hash collisions

You can actually catch collisions with extra 64 bits stored in TT entries. This will be another hashkey computed using a different hashing formula. The chances of two positions colliding twice when using two different hashing formulas is almost non-existent. I wonder if using two 64-bit zobrist hash...
