after 26 days the Top8 unltimate tournament (90 +30, 4cpu, ponder ON) is finnished. Average game time was 3 hrs and 50 minutes.
I was surprised, because I estimated 4,5 hrs.
Here a little statistics:
Games : 168 (finished)
White Wins : 60 (35.7 %)
Black Wins : 33 (19.6 %)
Draws : 75 (44.6 %)
Unfinished : 0
White Perf. : 58.0 %
Black Perf. : 42.0 %
ECO A = 20 Games (11.9 %)
ECO B = 57 Games (33.9 %)
ECO C = 26 Games (15.5 %)
ECO D = 40 Games (23.8 %)
ECO E = 25 Games (14.9 %)
all in all : Only the top 3 engines are placed as in the ratinglists. It was a thrilling and interesting tour.
If pondering is an advantage for some engines, I am unclear yet. I think the timecontol with 30 sec increment has more influence to the tournament.
Rybka 3 dynamic won as expected.
Naum 4 clear number 2.
Shredder does verry well and was long time on place 2 or 3.
Fritz found late but powerfull into the tour.
ClusterToga on place 5 *happy*. This shows again the power of CT's YBWC parallelization by Kai Himstedt.
I estimate on 4cpu a + of 60 "ELO" points compared to its original Toga II 1.4beta5c.
Zappa only place 6.
Hiarcs and Sjeng at the last places, but in some games they showed their power ! I got a hint to switch of optimistic search in hiarcs.
Should be better in long time controls. I will try that!
