Re: What is the strongest python engine?

Now it looks like we have the number of a CCRL 2445 engine in 3+2. Only tweak was a little prefetching of high policy children which doubled the nps. I'm tempted to go mutithreaded, but I want to keep the code simple. [Event "?"] [Site "?"] [Date "2020.03.21"] [Round "1"] [White "A0Lite"] [Black "Tu...

What is the strongest python engine?

I’m putting the finishing touches on my engine, a0lite. It uses the badgyal-8 network — a Frankenstein monster trained up on lichess games and shallow sf multipv search — and is written entirely in python. I’ve been looking for sparring partners that are also written in python. So far the only vague...

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

I believe this should be the real challenge for programmers now, adding Elo is getting boring (although necessary for some engines). Leela has done something on this front. Small nets and small search result in a very different playing style than a crippled Thinker. https://lichess.org/@/leela2200 ...

Fat Fritz, SV 3010 and the Nimzo-Indian

After testing t60 and FF in the Najdorf, I decided to step up to the big nets: Sergio’s 384x30 nets trained on t60 games. I had to extend the TC so the big net got enough nodes. A bit past halfway. Let’s see how we go. 3... Bb4 plus the most popular lines 1 ply after that. TC 3 min + 2 sec. RTX 2070...
