I did this test because I've always heard "35 or 36" as the accepted bf when doing a min-max search, and Vincent has been claiming that it's more like 40. Test 1: WAC1-100 (10 sec/mv) ==> avg bf = 34.29 Test 2: ECM98 (10 sec/mv) ==> avg bf = 36.85 So, I'll stick with "35 or 36". Ok, a few details. No qsearch, no null, no pruning of any kind, no hashing. Alpha was set to -inf and beta to +inf upon entry to the search. I measure bf after each completed iteration simply by doing: bf[iteration] = nodes[iteration] / nodes[iteration-1]; After each problem, I compute the average of the bf's for each completed iteration. After the entire suite, I use the average of the averages as the final bf. -- James
