I'm talking about my personal experience with Pharaon. I think engines can be good at one time control and relatively bad at others. I have played quite a few games with it in tournaments of long and short time controls. Based on my testing, I think pharaon is quite a bit better at long time controls. This is a few of my results with pharaon 3.1 recently. 4min games: 11th (last place): Pharaon 3.1 148.5/400 60min games: 8th place so far: Pharaon 3.1 16.0/39 40min per 40 moves: 4th place so far: Pharaon 3.1 7.5/12 >I do not claim nothing about long time control with no evidence. >I also think that generally strong programs in blitz are better at longer time >control. > >I remember claims that quark is better at long time control but I see no clear >evidence for it based on data. > >AEGT rating at 40/4 > >1 Pro Deo 1.0 : 2689 19 22 845 62.4 % 2601 25.9 % >2 Ruffian 1.0.5 : 2679 18 19 1046 60.9 % 2602 26.7 % >3 Aristarch 4.50 : 2639 19 16 1197 53.6 % 2614 28.6 % >4 SOS 4 : 2625 21 18 995 52.9 % 2605 26.1 % >6 Delfi 4.5 : 2617 22 17 990 51.2 % 2608 29.5 % >8 Tao 5.7 b07 : 2592 18 21 966 47.4 % 2610 26.5 % >9 Crafty 19.15 : 2587 24 27 530 42.8 % 2637 30.6 >%13 Yace 0.99.87 : 2579 19 22 824 45.6 % 2609 29.4 >% >14 Gothmog 1.0 beta 10 : 2564 22 23 741 43.5 % 2609 25.1 >% >15 Quark 2.35 : 2522 24 20 773 37.3 % 2612 25.7 >% > >AEGT rating at 40/40 > > >1 Ruffian 1.0.5 : 2679 31 33 334 63.2 % 2585 31.1 % >2 Pro Deo 1.0 : 2678 39 46 204 64.7 % 2573 26.5 % >3 Aristarch 4.50 : 2657 32 32 333 60.1 % 2587 30.6 % >5 Delfi 4.5 : 2638 34 30 324 57.1 % 2588 33.3 % >6 SOS 4 : 2634 38 47 208 65.1 % 2525 25.5 % >9 Tao 5.7 b04 : 2603 37 28 336 51.8 % 2590 31.5 % >10 Crafty 19.15 : 2592 37 26 336 52.2 % 2577 37.2 >% >12 Yace 0.99.87 : 2574 28 37 325 47.2 % 2593 33.5 >% >16 Quark 2.35 : 2551 31 34 335 43.7 % 2595 27.8 >% >18 Gothmog 1.0 B10 : 2546 29 37 327 47.4 % 2564 30.0 >% > > >You can see that the order is almost the same and the difference for Quark >between 4/40 and 40/40 is estimated to be less than 26 elo for long time >controland the possible error at long time control is bigger than 26 elo(I >calculated it by head so I hope no mistakes). > >Yace 57-23=34 >Crafty 65-41=24 >Tao 70-52=18 >Delfi 95-87=8 >Sos 103-83=20 >Aristarch 117-106=11 >Ruffian 157-128=29 >Pro deo 167-127=40 >Gothmog 42+5=47 >(34+24+18+8+20+11+29+40+47)/9=231/9<26 elo > > >You can see the rating lists in and I simply took programs that appear in both >lists > >http://www.husvankempen.de/nunn/40403012.txt >http://www.husvankempen.de/nunn/4043012.txt > >Uri
