a Telltale position

[Christopher Conkie]

I know you are watching Robert. Are you still trying to say that you did not use Robbolito as the code base for Houdini?

These are not similar ideas everyone can see here in these positions.

These two engines use the SAME code base.

Thats a FACT.

This does seem like strong evidence.

[frcha]

So is it confirmed then, irrefutable?

Houdini is multi-core optimized robo?

[Christopher Conkie]

So is it confirmed then, irrefutable?

Houdini is multi-core optimized robo?

The likelihood of it not being exactly that, is somewhere between nil and zero percent.

[Christopher Conkie]

Just thought I'd also say that these are not our positions. These are the positions that all you, the members, have posted over the past few weeks.

That includes both supporters of this Robbolito derivative and non-supporters of it.

It gave me a lovely warm feeling to know that those supporters would hang their hero by their own actions......

But then thats just me.......

[John_F]

So these words "based on" and "taking ideas from" have different meanings and can be interpreted how ever you want.I wonder why he choose to also take the bad ideas too, like the evaluation of this position.I just wish that some authors will come clean with their real contributions.We don't want a repeat of the Rybka-Fruit fiasco.
Is it possible to take code from other engine and then change it ever so slightly and then turn around with a straight face and say you only took the idea?You may be able to kid others but not yourself.

I never read that the author of Houdini claimed that he only took ideas and did not take code.

He said that he took ideas from different sources and it does not contradict taking code.

I was curious about this also, Uri.

Jeremy Bernstein of Open Chess also says that Robert Houdart claims that he has used no code from Robbolito.

But I do not recall reading that Robert specifically stated such. He says he used "ideas" from other engines. I suppose this could be read as tacitly claiming (or implying) code from Robbolito was not used since he does not say that he did. But, AFAIK, he also does not specifically state that he did not. Maybe he wrote something else on it that I missed.

so you seriously think houdini is just a better smp version of ivanhoe?

It started as Robbolito just as Ivanhoe did.

I'm deadly serious.

i believe the code base is ippolit. but it's not optimized for mutli-core. it's legitimately improved upon open source code. it's a fact it scales worse than rybka.
