A hot topic on CCC these days seems to be how hardware and software advances in computerchess correlate during the last 10 years. After reading a lot of interesting posts this morning I felt inspired to do a little experiment. Mark Young wants to do experiments with older programs on present hardware and is convinced he'll find out that the newer programs will show considerable progress. I agree to his expectations. A few posters suggested that top chessprograms advanced about 200 ELO points in software alone in the last 10 years . Depends .. New programs will take advance of the superior hardware availlable also in design probably - so this test should be taken into both directions IMHO. So - looking around in my room my eyes suddenly feel on a dusty 486 computer sleeping in the corner of my room - and then suddenly my Palm began to beep in the briefcase ( the truth , not made-up) . In advance : there has been convincing data posted that Chess Tiger on a Palm is probably stronger than Chess Genius on a Palm by Werner Schuele. As Chess Genius on a Palm is said to be a port of the Mephisto Roma to Palm architecture we are talking about at least 14 years of development here though. So the contenders : Genius 4 ( which isn't supposed to be superior to Genius 3 in public opinion - so 10 years isn't far away) on my 486DX50 computer ( in fact I don't really remember if it is 50 or 33 Mhz and dunno how to test) - so let's assume the 50 here with 4 MB RAM , so 1 MB availlable for hash -> clearly a program of the past against ChessTiger 14.1 on Palm Vx overclocked as much as possible with AfterBurner -> clearly a present top program I am no hardware freak so if this is very unfair I should be informed - it's simply what was availlable here. I decided on games in 15 minutes ( dunno why ) . It probably should be added that I am a fan of the ChessTiger program now and have been a fan of ChessGenius in the past- so I was simply curious . Today ( day 1 ) there were five games - then my Palm reported that it soon wants new energy now which has to wait until the weekend . So - to be continued when refuelled .. pete A few general observations: Chess Tiger seemed to seek ~1 ply deeper most of the time . Chess Genius seemed to have superior endgame knowledge where Chess Tiger seemed to rely on its search only in similar situations . Both opponents seem to be very close in strength. There haven't been enough games played yet for _any_ statistical significance :) . A few extremely brief comments on the games : Game 1 : 15. Ba6 ?! is a quite typical unpositional move by Chess Genius- close to draw all the time Game 2 : Out of the opening straight into the draw Game 3 : 8. ..Nb6 ?! by ChessTiger kind of sucks - 24. ...Nc4 ? is blunderday . Game 4 : Draw - no comment by me Game 5 : This should have been Tiger's game. 10. ...e5 ?! looks unpositional though ; 24. ef ?? by Genius ; 26. ... Rxg2+ ? ( why ? ) , 52. ...Qe5 probably would have saved the game probably A few results : Chess Tiger 14.1 - Genius 4 1/2 1/2 0-1 1/2 0-1 => 1,5-3,5 so far A few conclusions : Looking at the games I don't expect ChessTiger to be 200 ELO superior - although I know anything can happen ..
