If sqrt(a*b/1000) is correct than it's: std.err sigma confidence gnubg/bgb = 15.79 2.28 ==> 98,8% gnubg/snowie = 15.81 1.39 ==> 91,8% gnubg/jelly = 15.53 11.98 ==> 100,0% (well, nearly) snowie/bgb = 15.81 0.51 ==> 69,5% snowie/jelly = 15.64 9.21 ==> 100,0% bgb/jelly = 15.77 4.31 ==> 100,0% So we can be quite sure that jellyfish will be beat by all other bots, we can be quite confident that gnubg is better than bgb, we can be a little confident that gnubg is better than snowie. Am I right ith these numbers? Ciao Achim _______________________________________________ Bug-gnubg mailing list Bug-gnubg@gnu.org http://lists.gnu.org/mailman/listinfo/bug-gnubg
