Correctly Implementing Zobrist Hashing

阅读更多关于 Correctly Implementing Zobrist Hashing

问题 I'm currently adding transposition tables in my chess engine, and I'm having issues with incrementally updating Zobrist keys. I did some research and implemented the basic idea, but it's not behaving as I expect. The problem I encountered was that equivalent board positions do not always have the same keys. For example, in the starting position, if both players just moved a knight and then moved it back, the key would be different from that of the starting position. However, doing this again

Print chess unicode characters in C++, and make characters square sized

阅读更多关于 Print chess unicode characters in C++, and make characters square sized

问题 I'd like to ask what's the simplest way of writing the chess unicode characters in a console window in C++? (♙♘♗♖♕♔♟♞♝♜♛♚) They are part of the "Miscellaneous Symbols" block in unicode. https://en.wikipedia.org/wiki/Chess_symbols_in_Unicode I also want to print characters with square size, right now my chess board is not square, because each character is a rectangle and not a square. It'd also be good to be able to write with ordinary non-square characters below the chess board, but that

Displaying unicode chess pieces in Windows-console

阅读更多关于 Displaying unicode chess pieces in Windows-console

问题 I've been developing a console Chess-game in C++ (using MVS2010) and I seem to have faced a problem I cannot solve on my own. The matter is that I need to have the following chess pieces displayed in console: http://en.wikipedia.org/wiki/Chess_symbols_in_Unicode I certainly went through a great amount of forums, articles and documentations and still does not have the task done. I understand that some characters (in particular, the ones I need) cannot be displayed using fonts provided by

efficient storage of a chess position

阅读更多关于 efficient storage of a chess position

问题 I've read tons of web hits related to this issue, and I still haven't come across any definitive answer. What I'd like to do is to make a database of chess positions, capable of identifying transpositions (generally which pieces are on which squares). EDIT: it should also be capable to identify similar (but not exactly identical) positions. This is a discussion almost 20 years ago (when space was an issue): https://groups.google.com/forum/#!topic/rec.games.chess.computer/wVyS3tftZAA One of

Ok, thanks in advance!

How to get actual move rather than move value from mini max algorithm

阅读更多关于 How to get actual move rather than move value from mini max algorithm

I am currently writing a minimax algorithm with alpha beta pruning for Chess. From all the examples I have seen, minimax algorithm will return an int value that represents that best score or board state that will result from the best move. My question is how can we return the best move that is associated with the score return value? For example, my alphabeta() in pseudo below ... public int alphabeta(int depth, Board b, int alpha, int beta, boolean maxPlayer) { if(depth == 0) return evaluateBoard(b); if(maxPlayer) { for(each of max player's moves) { // make move on a tempBoard int eval =

fast heuristic algorithm for n queens (n > 1000)

阅读更多关于 fast heuristic algorithm for n queens (n > 1000)

问题 I write two program : put together n queens in chess board without any threatening by backtracking algorithm. but that is very heavy for big n . at last you can run that for 100 queens. put together n queens in chess board without any threatening by Hill climbing algorithm. this algorithm better than past solution but it take 2 min for 300 queens and this time increase exponentially! But I didn't have any idea for doing that fast! I want algorithm for doing that faster . I want faster manner

How can I effectively encode/decode a compressed position description?

阅读更多关于 How can I effectively encode/decode a compressed position description?

问题 I am writing a tablebase for a Japanese chess variant. To index the table base, I encode each chess position as an integer. In one of the encoding steps, I encode where the pieces are on the board. Since the actual method is a bit complicated, let me explain the problem in a simplified manner. The Encoding In the endgame tablebase, I have (let's say) six distinct chess pieces that I want to distribute over a board with 9 squares. I can naïvely represent their positions by a six-tuple ( a , b

how to communicate with uci protocol using matlab

I'm looking for a method to communicate with a chess engine with uci protocol using matlab. The chess engine is rybka and its an exe file. When I run the rybka.exe, I can communicate via dos command prompt but I want do that via matlab. I think I have to use streampipe and stdin and stdout but I don't know how use it. I found this code in Python and it works fine but I'm looking for a matlab version: import subprocess, time engine = subprocess.Popen( 'a.exe', universal_newlines=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, ) def put(command): print('\nyou:\n\t'+command) engine.stdin
