Since the positions are with in 6 men it returns the correct result immediately. Search depth goes to maximum = 100, but it will not give you PV.

You can get a PV by not probing the EGTB in PV nodes. This is what I do in GNU Chess.

This is a relatively common design pattern in C.

pointer!=NULL => pointer valid

(for allocated pointers).

If you want to reuse a non NULL pointer, free it first (e.g. implicitly as in realloc). The contract says that the free is automatically legal.

This allows you to do primitive object ...

A final remark: it seems that it the current setting, with -1.5 and 4.5 Elo as goalposts, one is making an inherent assumption the prior distribution has the same values at these points. That is, a patch worth -1.5 Elo and one worth 4.5 Elo are equally likely to occur. OTOH, even if this is not ...

"I feel the program Crafty is no longer in the top 100 programs. I feel it is a run of the mill program now much like the author."

I made the above statements at CCC and the post was removed and Julien's PM told me I am libel. I broke some sort of CCC rule.

Telling the truth does not make someone ...

Has anyone put Remi's new optimization tool to use on a cluster yet? Bob? If so, what kind of improvements are you seeing?

On a cluster with N identical computers testing time is divided by N.

As for identifying the currently active engine, that feature is already in the v3.0 version!

Ok thanks!

I may implement the option to replace the built-in engine permanently by an imported UCI engine though.....

This is something I would like. Of course it should not really be permanent. It should be possible to reimport the built-in engine.

Also: I am often confused which engine is currrently ...

Please explain case-1. how can -8 -8 (Fruit) change into -504 and -588 (rybka)? It should have been either -504/-504 or -588/-588. Correct?

Case-2. How can 0 change into 84? 0 multiplied with any number still remains 0.

Case-3. The weirdest of all. The red in Rybka should produce far higher ...

That's a quite an erroneous statement in my opinion, because at some time both Loop/List were commercially available, which shows the fact that there was a whole lot more than just research into algorithms. He could have published his work as an open source, but he did not, which shows that he ...

I don't quite know the history but didn't Fritz Reul get a PhD for writing Loop?
