Hi! This Spider 080621 is better than Spider 1.1d, right?

I didnt see a topic for Ditto so Im posting one here.

Ditto was released by Michael Byrne as a Cfish clone in February of this year. It hasnt been updated since that release... So here I present an updated Ditto.

The updates are precisely in line with the Cfish patches implemented by syzygy1 (the creator of Cfish) as they currently sit on the date of this posting... With 1 single exception -- I had to leave the patch "Remove coordination between searching threads" instead of removing it. If I remove it, the engine crashes... This has been confirmed by others that have used my builds in the past. It literally may only be me that has this problem... But if I build it with that removed, it WILL crash at minimum once per game on DroidFish, and usually more than that. No idea why, thats simply the way it is.

So, heres the engine for Android armv8...

Here is the official Github for Ditto on Michael Byrnes page...https://github.com/MichaelB7/Cfish/tree/ditto

For anyone interested, I also have another version that I updated with official, handpicked [by me obviously]
Stockfish patches thatve been implemented since the larger net was introduced. Im not saying I added the new net architecture to Ditto, just that I added some of the post-new net patches I felt were helpful in increasing elo, to it. Send me a PM for this version. I have NOT tested the 2 against each other yet... So I don't currently know which is the stronger of the 2.

1 more relevant note... The engine I provided does not come with an embedded net, so Ive added the default net to the folder with Ditto. This must go in the same file as the engine, OR the FULL path to the location of the net must be written in Dittos "EvalFile" option.

If using DroidFish, you only have to physically place the net in the /DroidFish/uci/logs file and you shouldn't have to do anything beyond that. ONLY place the nnue net in the logs file, the engines go in the uci folder. Im assuming most using DroidFish already know this though.

Collected with GCC? Have you overcome the error (profile count data file not found [-Wmissing-profile] when building the PGO version in Termux?
