Re: Automated comparison of human chess players

I mean using a static value such as excluding the first 8 moves of the game, or excluding moves after move 40. Maybe the opening lasts until move 10 or 12, or maybe the endgame does not start until move 44 :)

Automated comparison of human chess players

I read this and saw this . The idea is comparing human games against the computer analysis and calculating the average margin of error, and presumably we can use this to determine which player played better over a period of time. I would be interested in doing the same analysis of the current top pl...

Re: Methods for playing human-like chess

I think it's an interesting goal, and efforts to this goal would be more beneficial to the improving chess player than adding more Elo points to the top engines. I think we would first need a database of games from a range of non-masters. I recall someone had harvested every FICS game at one point. ...

Methods for playing human-like chess

What are the current methods used to make engines play more like humans? Are those methods effective, or do they still need improvement? Which engine plays the most like a human?

Re: (Where)Can Stockfish Improve?

I've lately started to take interests in Stockfish code. My Questions are: 1. Can Stockfish improve? 2. How much can Stockfish improve (I've heard sky is the limit)? 3. WHERE can it improve? (Opening, Midgame, or Endgame, or evaluation, or search, or move generation, or code optimization?) I think ...

Position validity

What are the minimum requirements to have a valid position when loading from FEN? Is it only that there are two kings, a valid side to move, and side-not-to-move is not in check?

Re: Increasing the performances !

I am actually still working on this, but since my current attempts at Cython are failing, I might give up and go back to Python. What are you trying and how is it failing? I have always been interested in Cython, but it seemed like I always ended up writing C-looking code in Python, so I didn't see...

Re: Move encoding

Hi Gerd, do you mean you have a list of bitboards that serve as your move list?
