Subject: A proposed WAC replacement for testing

Author: Gian-Carlo Pascutto

Date: 10:05:08 09/18/01


Like many others here, I use a standard testset
for testing improvements and doing regression
testing to my engine.

So far WAC has been adequate, but as you all
know it has two annoying problems, namely that
over 2/3 of the problems are solved by 2 ply
searches and hence useless, and the level of
most of the others isn't very hard either with
nowadays CPU's.

ECM could have been better, but it's very big
(over 800 positions) and contains a lot of garbage.

Based on some parts of ECM I got from Dann's
ftp and a day with Goliath Light, Hiarcs and
my common sense I filtered 200 positions of
varying difficulty which have, as far as I could
tell and verify, correct solutions.
The suite is meant for relatively quick testing
of improvements and/or regressions. The recommended
time is 10 seconds per position. Running all
positions takes a little over half an hour. It
is what I currently use instead of WAC.

I would appreciate feedback about the positions,
especially if you think there is an incorrect
or dual soltion. Performance data of other amateur
or professional programs is appreciated too.
My latest Sjeng gets 80/200 at 10s on an Athlon 1000.
