Strelka: Justice in Reverse

[fern]

I believed to date, how candid am I, that every normal intelligent person already knew that you must be considered not guilty until proofs on the contrary could appear. Now I see that in this field of chess computers the very opposite is the norm: you are considered a felon unless you probe the contrary.
Is Trelka a clone or not?
If it is, sooner or later proofs of it will appear. In the meantime decency, trust and simple good will call to accept the claim of the author.
Have you forgotten what happened when Rybka father came here and said he had a lot stronger engine than any other?
Almost all laughed at him. First feeling was untrust. First movement was to reject. First gesture was to deride. All this does no speak of a community with a sane state of the soul.
Is not smarter, at last, to be nice and accept the claims and then later see if they are for real? Always you know the truth at last, isn't it? So, for what to spread poison in advance that perhaps you will be compelled to swallow?
In brief, to ask Trelka author proofs of NOT being a felon is, in my feeling, the very opposite of reasonnable good will and justice.
Those that believes it is a clone must be the people to make an effort to probe that.
Otherwise we are installing here a kind of totalitarian court as those in URSS 30's years. And worst, an spirit of bad faith.

I never ask questions if I know something is ok.

this has been done

maybe you missed the positions where they played similar.

I don´t understand nothing of programer, but I agree with Fernando.
Do you are sure that it´s a clone? 100% sure? If not, I will remember
to you that you are calumniating the author. And about the damages, moral
and probably comercial?

[fern]

If that is a proof, is not a very good one. Many engines play the same in similar situations because they are good enough to see, equally, all of them, the best path.

thorsten look at that game (especially at evaluation in the end) and tell me again that Strelka is Rybka clone:

[mclane]

you can agree as often as you wish with fernando. that is your right.
there were positions mentioned in several forums. where strelka behaved similar to rybka.

[mclane]

but they do not reproduce the same bugs.

[fern]

Wait, thorsten.
Consider this.
A bug is something wrong IN the code.
By example, in BASIC...

10 Print "fernando"
20 goto 10
run

there you have a loop that causes an stupid repetitions of my name being printed. You could call that a bug.

Now, a certain kind of baheviour, the thing you can see in the game, can comes from many sources. I dare to say that very different codes can give as a result the same behaviour. As we have seen here many times, in certain positions ALL or many programs give same bad move as an answer and they are all different.
In that case there is a common "game-bug", but not necceasarily -in fact, not at all- same code-bug
