Subject: Re: The failure of validation with DEEP BLUE 2 (ethical questions)

Go up one level in this thread



It seems that most of the controversy can be boiled down to the axb5 vs Qb6
issue.  This was the ONE BIG evidence Kasparov had of possible cheating.  It
seems in fact that this is the only thread by which the cheating allegation
hangs.  If that could be demonstrated, then who knew how many more moves in the
match would have been "corrupt", yes?

But we find that logs from other chess engines show a similar DB2-like regard
for the two moves over time in that the two evaluations show a trend toward
intersection.  This greatly weakens (if not completely destroy's) Kasparov's
strongest evidence of cheating.

All the rest of the arguments about courtesy, politeness, friendliness, supposed
sinister motives (please provide Hsu's and Murray's brain logs for evidence!)
and goodwill do not strengthen Kasparov's axb6/Qb6 contention, by which the
entire cheating allegation hangs.  That is the only thread Kasparov ever had.
And his contention has been scientifically undermined, if not completely
destroyed.

_That_ is science.  If it's good enough for other engines to find the evaluation
trend, if not the move itself (given the un-avoidable technological
disparities), then the DB2 log validity is only strengthened, not weakened.

That's where the true scientific evidence points.  End of story.  Game over.

Yes? :-)
