Simple induction. No It is not clear. Even if you assume that the programs are equal at all time controls It is also possible that the 2 programs have the same branching factor when program A needs time for the first iteration. There was a claim that programs with smaller branching factor are better programs and that Genius was bad at long time control because of bad branching factor. I think that the main problem of Genius at long time control was the fact that it did not do extensions of more than 12 plies. I do not say that I can learn from the experiment which program earns more from time but I can learn more information if I have also the branching factor of the programs at different depthes. Uri
