Re: Forbidden

With regional IP block, you sure you are preventing more hackers than normal users? :D

Re: Which is stronger AlphaZero( 5000 TPU) or Stockfish(30.000 Cores)

If your alien race is far more advanced then I see no reason to send our poor imitations of human intelligence than our top human chess player. Their computers will probably run our crappy programs much faster but our biological evolution and individual personalities are something they will never ha...

Re: Using Freeware AI and Dynamically Generated Endgame Tablebases

Well there is the problem: people so far have no meaningful way to describe how those networks work. Currently networks contain huge number of parameters and they correlate in mysterious ways to produce the outputs, that is also why large numbers of games are needed to train those networks so that t...

Re: Using Freeware AI and Dynamically Generated Endgame Tablebases

To simplify what I said, or I understand you correctly about the approach: Take a position with a few pieces, a bit more than(or within) existing EGTB coverage, and start generating games, train on the resulting games and try to improve the next iteration until it can predict the correct move with h...

Re: Using Freeware AI and Dynamically Generated Endgame Tablebases

Well, this usually ends up with some very over-fitted networks because you are intentionally limiting its training sample diversity. Such raw database exists, with billions of positions and most of their moves analyzed at reasonable depth, although I fear it is never going to be enough to train a ne...

Re: Using Freeware AI and Dynamically Generated Endgame Tablebases

There is a conceptional difference between "an exhaustive enumeration of subsequent positions given a certain position" and "an exhaustive enumeration of every possible positions given a certain set of material". The former is essentially a search without any pruning, functionally being a special ca...

Re: Poor mans testing process please

Even on the other side, people are using more and more comprehensive testing procedures What do you mean by "on the other side"? It means where a significant portion of the engine is not written in comprehensible code where one can accept or reject certain part of its changes. This is on the opposi...

Re: Poor mans testing process please

There are established testing frameworks and with the effort of some communications there are "free" compute resources available to conduct reasonably conclusive tests in a timely manner. Even on the other side, people are using more and more comprehensive testing procedures, so chess-related develo...

Re: Chess Cloud Database Query Interface

Flipping colors of the board is not exactly the same as "reaching certain position with which side to move", they are different concepts. Positive scores and negative scores have different weighted averaging windows, it may be similar to what some engines did. Internally, CDB counts the shortest lin...
