I think OP was referring to Gary Linscott who has made major contributions to both Stockfish and made an adaptation of Leela Zero to Chess, now living under the Leela Chess Zero Github org but apparently a different adaptation is now the officially sanctioned one, at least his commits don't show up in the new lc0 repo. https://github.com/official-stockfish/Stockfish/graphs/contr... https://github.com/LeelaChessZero/lczero/graphs/contributors

LeelaChess is one example for Chess. https://github.com/LeelaChessZero/lczero

Generally an "undisputed champion" title would require a level of effort that the AlphaZero team apparently isn't interested in. They like to run matches between AlphaZero and Stockfish in private under their own controlled conditions, and publish the results. The rest of the computer chess world likes to run tournaments in full public view, and there are several entities which run tournaments between engines that way which can be used to gauge the relative strength of the engines. What will be interesting is to see the effect on Leela (https://github.com/LeelaChessZero/lczero), which is public and open-source, takes part in public tournaments, and is built -- as much as possible, based on what's been disclosed in the papers -- to use the same approach as AlphaZero.

There is ongoing open source, community based effort to replicate Alpha Zero Chess. The effort is lead by Gary Linscott. He is also one of the main developers of Stockfish (I believe the framework for testing Stockfish). https://github.com/LeelaChessZero/lczero Here is the current state of the effort: https://docs.google.com/spreadsheets/d/18UWR4FVhPi0vNwwPreu_... Estimated date of surpassing Stockfish with settings and hardware reported in the spreadsheet is the end of this year. @edit I have missed your statements about symbolic reasoning. Yes, I'm referring to the same type of symbolic reasoning as the author of the article. I.e. system that manipulates high-level symbols without any grounded understanding of them in the surrounding us reality. Deliberating whether it is thinking or not is pointless. It's effective and that matters.
