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...

Re: Chess Cloud Database Query Interface

The back propagation of scores consider many factors: it does not prefer draws, a small penalty is given for non-progression, the number of counter-moves and their score contribution to the final weighted average score. White and black are not strictly treated equally to prevent those effects to cas...

Re: Banksia GUI released

If this is HTTP code 406 from the server, then you might want to add more "Accept-???" headers as per curl or wget sends in your request.

Re: Banksia GUI released

The link gives the following in response: "content-type: application/x-chess-pgn".
How does your library handle such uncommon MIME type? From the error message, it seems paranoid about it and you may want to find a way to handle it as "text/plain".

Re: ChessDBCN

Calling API over the Internet for learning at any meaningful scale is not efficient, you should then set up local environment from my data snapshots and make changes to API as you see fit.

Re: ChessDBCN

I asked if there is a mean to obtain, via code and for a given position, the best move and its associated depth, score and winrate. Providing depth to any move require recursive probing within the database which is quite resource heavy, so it is only performed upon explicit request. The move sugges...

Re: Move repetitions in tree search + transpositions

I don't know if it is worth the trouble to reconstruct the entire shortest line(which may not be actually short), if the longer history that gets fed into NN (which is truncated) has virtually no influence in detecting repetitions. To avoid exploring them unnecessarily just expand them when they are...

Noob is only saying this cause is experimenting with extreme BIOS settings and expect them to work…
Exactly the opposite, I have no interest in trying anything other than defaults, and that is precisely my complaint is about.

Re: Database snapshot

s this database snapshot the same as the one accessible from https://www.chessdb.cn/queryc_en/ ? Something I noticed was that it had reached and surpassed 9000000K positions, but every time it'd go up eventually it'd go back to sub 9000000K. But recently it has gone down to 5000000K as if almost ha...
