I'm testing an aggresive prunning method in my program. I believe best testing comes from real games, but I was curious how this change would affect tests suites results. So I tried the test from GPC site with the two versions, with and without aggresive prunning. I used my old PII 400 and 30 seconds for position. I have no experience with these epd tests and the result confuses me. It seems to randomly depend on the used time that a version does better or worse. Here are the results (by EPD2WB): Normal version: New version: Sec Solved Total Sec Solved Total ---- ------ ------ ---- ------ ------ 1 6 6 + 1 2 2 - 2 1 7 + 2 2 4 - 3 0 7 = 3 3 7 = 4 7 14 - 4 11 18 + 5 6 20 - 5 5 23 + 6 8 28 - 6 6 29 + 7 3 31 - 7 5 34 + 8 4 35 = 8 1 35 = 9 2 37 + 9 1 36 - 10 1 38 - 10 4 40 + 11 2 40 = 11 0 40 = 12 3 43 = 12 3 43 = 13 2 45 = 13 2 45 = 14 0 45 - 14 1 46 + 15 1 46 - 15 2 48 + 16 6 52 + 16 1 49 - 17 1 53 + 17 2 51 - 18 3 56 + 18 2 53 - 19 1 57 + 19 0 53 - 20 1 58 + 20 3 56 - 21 1 59 + 21 2 58 - 22 0 59 = 22 1 59 = 23 1 60 + 23 0 59 - 24 1 61 - 24 3 62 + 25 1 62 - 25 1 63 + 26 3 65 + 26 1 64 - 27 3 68 + 27 2 66 - 28 1 69 + 28 0 66 - 29 1 70 + 29 0 66 - 30 1 70 + 30 1 67 - I've put a (+) when one version does better at n seconds, a (=) for equal performance and a (-) for worse. So what's your experience in this matter? How would you interpret the results? Thanks in advance, José C.
