From: Simon Plouffe Newsgroups: sci.math Subject: about lattice algorithms Date: 31 Oct 1995 21:43:43 GMT Perhaps a look at what Maple can do with that kind of problem would be interesting. With a maple session type --> ?lattice I think the lattice algorithm of Maple is about 5 times faster than Mathematica. If you want a MUCH faster program to do the same (lattice reduction algorithm) there is a program called PARI-Gp available with FTP and it is 100 times faster. The command is LINDEP. For a 'state of the art' version of that same idea there is the program of David H bailey of NASA called PSLQ that does exactly that, that program goes with MPFUN a multiple precision library in fortran. The source of these programs are available at the netlib depository. I hope this help.
