Re: a Telltale position
So it appears that some of you have reinvented the wheel for the 4285th time in attempting to prove that the original Ippolit/Robbilito/whatever series is a derivative of Rybka 2.3.2a or whichever version.
Would somebody mind running the same tests on Rybka 1.0 beta and the version of Fruit that it was allegedly taken from?

This production is being brought to you by Rybka: "The engine made from scratch.™"

Well i suppose that is a "plus" side to it.......

Re: a Telltale position
The evidence seems overwhelming. I wish Robert had simply admitted up front that Houdini was a modified Robbolito, and that he had released his source code all along. Clearly his modifications have significantly improved what he began with, and incorporating a parallel search seems a non-trivial addition. But now the charade is ended, and I'm afraid he ends up looking bad.Christopher Conkie wrote:It started as Robbolito just as Ivanhoe did.yanquis1972 wrote:so you seriously think houdini is just a better smp version of ivanhoe?Christopher Conkie wrote:The likelihood of it not being exactly that, is somewhere between nil and zero percent.frcha wrote:So is it confirmed then, irrefutable?

Re: a Telltale position
It is a bit sad and disturbing, because Robert Houdart usually appears like a nice, knowledgeable and fairly levelheaded person...

Re: a Telltale position
No, Komodo goes to some trouble to make sure the values of the pieces are centered. We have a mobility adjustment factor so that low mobility is actually negative and the pieces square tables have negative as well as positive values in them too. It should not be the case for us that we have to use low base values for pieces to compensate for all the bonuses we might give.SuneF wrote:When you say 'the value for minors' I assume you are speaking of the material score. In the evaluation, as you probably know too well, it all gets added up to a single number. When you have 3 minors vs a queen and you are just considering the material side of things it may seem the queen is overestimated, but the 3 minors will often add up to more when considering all the other terms - like mobility. If you consider the average value of the queen vs the average value of a minor it should get closer to a GMs assessment I think. It's just that estimating the average value of a piece is not so easy.lkaufman wrote:I feel that if a program does not see White's edge in the given position it is probably just undervaluing minor pieces. However a specific bonus for three minors vs. queen is the easiest fix here, I'm pretty sure your program must consistently overvalue the queen's side of this equation. It remains a mystery to me why the optimum value for minors (compared to majors) seems to be lower for engines than for humans. The values (for minors) that tested as best in Rybka are clearly too low to human eyes. That's why I always used Rybka 3 Human rather than the default for analysis of human games, it had the values much closer to what we human GMs think best.

This is really one of the big problems with writing and tuning the evaluation, the terms are not orthogonal.

As long as he is not charging any money for his improved Robbo open source based engine I am not complaining, as well as all others who are using it, and there are many...
