Subject: Re: Are comments about Crafty 16.6 to harsh or just accurate observations?

Go up one level in this thread


With regard to your first item, whether Crafty is on par with the top
commercials is IRRELEVANT to me. The author wrote an article ostensibly about
the commercial chess programs, then bit into Crafty (not even commercial) for
some reason, then reviewed the programs which shoulud have been the focus of his
article under the heading "Some other commercial programs," then ignored his own
data that refuted his conclusions about Crafty. Whether you agree or disagree
about Crafty, that is very poor science.

With regard to your second item, YOUR observations about Crafty may or may not
be accurate. I do not know. I do know, however, that when you draw conclusions
from data, you ought to do so in a nonbiased manner. You ought not ignore your
own findngs, as the author does.

With regard to your third and fourth items, from my perspective, Crafty's play
is beside the point. If you want to start a disinterested and constructive
thread on Crafty's play, you could certainly pick a better time to do it than
when political rivalries are simmering. You would have to be interpersonally
oblivious to believe that the title of your post makes you look anything less
than disingenuous.

With regard to your fifth item, you miss the point again. The issue is NOT
crafty's play, the issue is whether the generalizations made from the data were
made in a disinterested, scientific manner, rather than a political one.
Certainly it is possible that some of the author's assertions were accurate to
some extent. But I can't trust his conclusions, you see, because he choose to
ignore his own data, and because the way the article is structured certainly
makes it appear as a hacket job. The motives are of the article are clear.

If you are sincerely interested in the play of "classic" versions of Crafty, as
the header of this thread indicates, you could definitely pick a better time.
You really do look as if you are taking sides.
