There was a bug in Cyclical Time Controls and Arena analysis, this fixes both.

This release is using a new (embedded) net named "nimble nothingness" (not compatible with previous release): this net was trained on 2B FRC Minic data (from "nucleated neurulation" at depth 10 to 14).

Minic 3.18 includes some juicy fast TC patches but I'm quite sure they don't scale at LTC unfortunatly. It's anyway expected around +60Elo versus previous release.

One kind person shared with me a chess engine Fisherov NNUE 0.98b4 arm7 + arm64. I decided to share it in this topic dedicated to the engines for Android. Here is a link to download.

I'm interested in seeing your behavior "Aleksey52", it's better if you want to upload a file you should make your own post so that all members know it, or better upload it on the Droidfish chess engine in this forum, this is Archimedes' topic, don't disturb the posts with your posts. I'm afraid other users will find it annoying too

Absolute no problem, to post it here. The only reason, why i create an own thread, was, because there also exists chess engines based on the xboard protocol. Therefore i choose a more common thread title.

Thank you sir for the good work. Kindly upload Stockfish+ (mcts) for Android. Much appreciated! Please, should the mcts option be turned on or left on default (which is off)? Thank you once again sir.

Don't understand your question. When you want to use MCTS, turn it on, when not, let it off. When MCTS is off, engine plays (should play) identical as the original Stockfish.

Can you tell me the difference between having on or off ? for example playstyle changes.

If you want to know how MCTS working (effect of MC Tree Search) just read this. https://www.chessprogramming.org/Monte-Carlo_Tree_Search
Having MCTS option on, engine will be about 50-60 elo weaker, see Dragon 2.6 vs Dragon 2.6 MCTS results here. https://www.sp-cc.de/index.htm

Mode for MCTS is now the same as used in BrainLearn and ShashChess. Nodes and nodes per second are shown correctly now.

It is good that there are many chess engines of different strength, the more interesting to arrange the fight between them.
Here is another Chess Machine Pedone 3.1.7 dated 25.04.2021 only for ARM64.
Homepage - https://sites.google.com/site/pedonechess

The engine weighs 25 MB, but it looks like it without NNUE. The power of his game is below average. Of the ten parties for 3 seconds on the move against the Texel engine 15.11.2021. Texel won with a score of 4: 2 and was 4 draws.

Maybe Archimedes or you could try to compile for Android also Fat Titz 2.0 220111 by Sopel...

Fat Titz 2.0 PC + source

Thank you, Alex

This is the first release since fully porting the engine to Rust, and so that is by far the biggest change. This release also includes multithreading for the first time via Lazy SMP, the introduction of Static Exchange Evaluation, a switch to Principal Variation Search, and a host of minor optimizations made possible by writing the engine in Rust rather than Java.
