- I have a file here, together with gnuchess.
- I have called it TODO. Whenever I feel like doing some
- gnuchess hacking I take a look in this file, choose something
- and then I do it.
-
- There is no priority on things they are just entered and given a number
- and when they are implemented I remove it.
-
- Here is the file, maybe you could prioritize these tasks and send
- them out to people who might have time to implement it.

-
- GNU CHESS - THINGS TO DO
-
- 4.Total Cleanup of SqValue.
-
- 5.The routine repetition() could use some form of hashing to check
- if the same position has occured before. The present implementation
- is quite slow. And it is also wrong since it considers only where a
- piece is placed not the type of the piece.
-
- 6.A tournament program to play chess between two different chess
- programs. This could be done by extending xchess so it could play
- two chess programs against each other. If such a beast exsisted we
- could play different versions of gnuchess against each other. And
- calculate ratings for different machines. A nodes/sec - rating table
- would be very nice to have. Also we could test different evaluation
- heuristics against each other.
-
- 7.A chess database to store historical games.
-
- 10.gnuchess does not handle stalemate correctly(is this still true?)
-
- 13.Convert the type of all time variables to time_t.
-
- 18.Check gnuchess compliance with GNU Coding Standards.
-
- 19.enum colors { white, black, neutral };
- enum pieces { no_piece, pawn, knight, bishop, rook, queen, king };
- enum squares { a1, a2, a3, a4, a5, a6, a7, a8,
- b1, b2, b3, b4, b5, b6, b7, b8,
- c1, c2, c3, c4, c5, c6, c7, c8,
- d1, d2, d3, d4, d5, d6, d7, d8,
- e1, e2, e3, e4, e5, e6, e7, e8,
- f1, f2, f3, f4, f5, f6, f7, f8,

- h1, h2 ,h3, h4, h5, h6, h7, h8 };

- 20.write more documentation
-
- 21.Fix this bug report

- Try moving a rook to row and and the undo (it becomes a pawn!!!)
- And also fix undo of promotions when using edit to setup a position.
-
- 22. Regression testing of strength against a bank
- of positions. The regression should compare
- performance between two releases, assess
- solution times, speed in nodes per second,
- accuracy of evaluation, and depth and then
- produce a comparison table, along with a final
- assessment of which version is superior.
-
- 23. Complete rework of the book, eliminating all
- illegal moves, providing a score for each
- variation with support code to enter variations
- based on the score.
-
- 24. An analyse mode, feed gnuchess with a game. gnuchess will
- analyse each posistion in that game giving it`s own principle
- variation and score and a principle variation and score for the
- played move, if they are not the same.
- ---
-
- ps. Maybe we could arrange some voting on the newsgroup gnu.chess
- for the most wanted feature in gnuchess.
