From the computer chess magazine Selective Search
by Eric Hallsworth
I maintain a 'Top Ten' coverage on the Internet, updating it from time
to time. The Selective Search Magazine Listings have more details,
including Ratings from games/matches v. human opposition, so I hope
Internet users will consider subscribing to it, as income I receive from Selective Search is an important part of my livelihood!
Selective Search Ratings
Each computer/program's rating figure is calculated by combining its computer-v-computer results WITH its results against graded players in
proper tournaments. The level of the finished List is determined by
the results v graded players. More computer-v-computer games are played than
those v-humans, as it is physically and financially impossible to obtain the
number of games of the latter type that we would wish.
Gradings from computer-v-computer results do not
always match those of a computer-v-humans, because a program CAN be
prepared specifically to do its best against other computers, OR it can be
programmed to do its best against humans! The latter is what USERS want, but
programmers inevitably have one eye on our Rating Lists, and are aware of the
preponderance of computer-v-computer games which helps produce them! Even so, my
view is that to have this type of Computer Rating List as an attempted measure
for the programmers and other interested parties, and as a guide for prospective
purchasers, is BETTER than to have no list at all, and SELECTIVE SEARCH does combine both types of result!
Please also note that the results on which my Ratings are
based do include (with permission) the valuable SSDF scores and, as the
calculations combine SO MANY results, I hope that they achieve a high level of
accuracy. The Ratings are initially calculated in British BCF figures, before
being converted to Elo figures using the formula (BCF * 8) + 600 = Elo.
The TOP RATINGS, including as far as possible all of the
NEWEST PC programs and dedicated CHESS COMPUTERS, are:

Ratings are calibrated to Pentium
Pro/MMX machines running at 300MHz.
