Tirsa Poppins has kindly made some builds:Gregory Owett wrote: ↑Wed May 29, 2019 2:18 pm Hi, Is there somewhere an .exe where you can download it ?
Sapeli 1.16 POPCNT and SSE3 bins:
http://www.mediafire.com/file/ghcgbgaeq ... p.zip/file
Or you can compile it by yourself from source code. There is also older builds listed: https://github.com/SamuraiDangyo/Sapeli
I have investigated the speed issue. Sapeli 1.16 actually has not lost any speed. It is faster. Eval just has gotten heavier. In fact Sapeli spends most time doing Eval(). When profiling Sapeli.

Re: Sapeli 1.0 - New chess engine
I released Sapeli 1.17.
Source code: https://github.com/SamuraiDangyo/Sapeli/tree/1.17
Release: https://github.com/SamuraiDangyo/Sapeli ... /tag/v1.17
More info about this version: https://github.com/SamuraiDangyo/Sapeli ... ns.txt#L38
Took my time to make this release. I wanted to make sure this is the fastest and strongest Sapeli version yet.
This Sapeli 1.17 should be really stable. I was able to find a few bugs.
As some people are using Sapeli for their engine development / testing purposes. Stability is absolutely necessary.
clang builds are super slow / Sapeli 1.17 = nodes 15764316 mnps 0.788
gcc = nodes 24037116 mnps 2.256

Re: Sapeli 1.0 - New chess engine
I published Sapeli 1.18.
I can't help myself. I'm always improving my engine.
Source code: https://github.com/SamuraiDangyo/Sapeli/tree/1.18-final
I noticed Sapeli reported mating score a bit wrong in xboard. + Very very tiny speed boost. No functional/strength difference to 1.17.
benchmark:
1.18
= nodes 66699488 mnps 2.223 time 30.001
1.17
= nodes 65602638 mnps 2.187 time 30.001
Thanks for testing Sapeli.
Very nice to see my engine in various tournaments!
Also great to see chess engines being written in languages such as Lua!

Sapeli 1.20
Windoze POPCNT and SSE3 bins
Mediafire: sapeli-120-tp.zip
Filedropper: sapeli-120-tp.zip
I find the release scheme followed by Ethereal and Xiphos most sensible: dev builds in the root dir (or subdir) reflect the latest commits, official releases reserved only for versions that offer significant (i.e. 20+Elo) strength increases or important new features.

Re: Sapeli 1.0 - New chess engine
Been improving Sapeli a little bit. Sapeli used to prune tactical moves too aggressively. Not anymore. Those are searched full depth always. Less stupid mistakes.
I added: Rook belongs to behind passed pawns. Own or enemy's.
https://github.com/SamuraiDangyo/Sapeli ... li.c#L2122
Sapeli 1.21 source code: https://github.com/SamuraiDangyo/Sapeli/tree/1.21
Currently 10-2-3 against 1.20 in 1 minute chess960 games. It is not worse. Probably not much stronger.
I keep the most stable and best version of Sapeli in master.
Also in own branch if I need to go back.
Some failed experiments like 1.20a / 1.20b / 1.21a etc are in their own branches. Those contain lots of work that just didn't work.
