Congratulations, *E.Pasma* ! You indeed won the "brute force sudoku speed" competition for sqlite 3.8.3 by a factor of x2.5 on my PC !
D. Richard Hipp is still tuning the CTE implementation, so competition may be less slow with 3.8.4. To get clother to python speed (http://norvig.com/sudoku.html), we would need to implement : - an efficient Peter Norvig's method, - or an efficient Dancing Links method. ==> See below link for "slower than brute force" dancing links implementation in pgSQL. http://www.postgresql.org/message-id/caj-6ajqpxxex8ftljksngksvbjrn0h3hydw9xpsvu837gsn...@mail.gmail.com regards, _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
