IIRC the RDTSC instruction is very slow, on the order of 50 cycles. In addition, I like having deterministic generators so that hypothetically I could reproduce any result.
In my chess program I use a modified version of Agner Fog's Ranrot. It's very fast and very random. There's a paper on his site on the theory behind it: http://www.agner.org/random/theory/ (the first link). You can see the actual generator I use here: http://zct.cvs.sourceforge.net/*checkout*/zct/zct/rand.c?revision=1.2 _______________________________________________ computer-go mailing list computer-go@computer-go.org http://www.computer-go.org/mailman/listinfo/computer-go/
