Re: The mystery of Alex Bernstein

Yep, Shura-Bura's Program, as mentioned in V. Tomanov (1961). The best move in 58 seconds. in the 8th Bulletin of the Botvinnik Tal 1961 revenge-match , was elaborated in Jaap van den Herik's Ph.D. thesis with some evaluation details and that it had no search. https://www.chessprogramming.org/Shura...

Re: The mystery of Alex Bernstein

Hi Sergei, thanks for your efforts to find some information on Bernstein. McCarthy's quote from The Dartmouth Workshop--as planned and as it happened is interesting: Alex Bernstein of IBM presented his chess program under construction. My reaction was to invent and recommend to him alpha-beta pruni...

Re: Widely unknown pioneering chess "paper machine" by Gunter Sсhliebs

How long must we wait until someone makes a Winboard or UCI port? I think it's easy to do using PyTuroChamp Shannon's program as the base, it will take not more than few minutes, but I want to examine the original Schliebs's article to be sure in details. For example mobility terms and search routi...

Widely unknown pioneering chess "paper machine" by Gunter Sсhliebs

Turochamp, Machiavelli, SOMA, SOMAC, Shannon's programs — we know a lot about them, even there are several reconstruction attempts especially by Chessbase team (Frederic Friedel, Martin Feist). However with a German attempts it is known a little. Zuse's first works on Plankalkül provides us with som...

The mystery of Alex Bernstein

It is well-known fact that the first fully functional chess-playing program was created by the team led by Alex Bernstein in 1957. It's surprisingly little known about him personally. No birth year, no bio, almost nothing. What I'm managed to discover: 1) He was one of the guys hired by IBM in 1956....

Re: One idea to solve chess?

EGTB's are desirable because they are FAST. The classic Time vs Space tradeoff. NN's are not even close to optimal models of any domain. Not even close. Keep that in mind, that its not even close. Let me say it again, that it is not even close. Very far from optimal. So very far. Let me say it agai...

Re: One idea to solve chess?

Let introduce me, I made a chess program in the 90s and organized one Spanish Computer Chess championship in Valencia, my city. Worked as an AI programmer in the videogame industry some years, and now on the internet sector. It looks, I've came the same idea :) See http://talkchess.com/forum3/viewt...

The Plan-9 to finally solve chess :)

An idea how to train NN to play chess w/o RL using only TBs. 1. Train some deep NN on 7-men tablebases. 2. Let's assume some trust men limit, initially L = 7. 3. Create empty minibatch for NN. 4. Gererate random L + 1 men position and perform N-ply search (optimal N value is disputable) val neg_valu...
