***Comments in (my bad) English***
The tournament RB 2002 is over. Each program had to play 10 games against the
other programs. If you look at the cross table, we have a clear winner with
Junior 5, a rather equal group of three programs (Yace 0.99.56, Aristarch 4.4,
List 4.61) and two less sucessful programs (Little Goliath 2000 v3.7 and Tao
5.4). But this impression is too facile. I would dare say that Junior5 is most
probably the strongest engine of all participants, however we can in no way say
for sure which of the other five programs is the best one. We have to bear in
mind the margin of error, and if doing so it becomes clear that statistically
spoken any of the programs in the RB 2002 tournament could have tied first
place. An insufficient number of games has been played in this tournament to say
something concrete. An example: Little Goliath 2000 v3.7 won with 7,5-2,5 vs Tao
5.4 but nobody knows if the result of the next 10 games between these two
programs would not be 2,5-7,5 in favour of Tao 5.4.
And look at the further interesting statistic. If we divide the 50 rounds RB
2002 into five separate tournaments of 10 rounds each, we can see - what a
surprise - that each program with the exception of Tao 5.4 would once have been
the winner.
In my opinion one must be very cautious in stating that program A is better than
program B. And without carefully studying the qualitiy of all games played in
this RB_2002 tournament, I can only say: it was just another tournament.
***Kommentare (gekürzt) in Deutsch***
Ein interessantes Turnier ging zu Ende. Die Tabelle sollte nicht falsch
interpretiert werden. Wohl sieht es so aus, als ob Junior5 tatsächlich das
stärkste Programm aller Teilnehmer ist. Statistisch betrachtet wurden jedoch zu
wenig Partien gespielt und die Fehlerquote in Betracht ziehend, hätte jedes
Programm den ersten Rang belegen können. Und was sagen Resultate wie LG2000 v3.7
- Tao 5.4 mit 7,5-2,5 aus? Wenig, denn die nächsten 10 Partien könnten umgekehrt
verlaufen. In diesem Sinne ist lehrreich, das Turnier in fünf separate Turniere
von je 10 Runden aufzuteilen. Dann sieht man, dass mit Ausnahme von Tao 5.4
jedes Programm einmal als Sieger vom Platz gegangen wäre.
Nach meiner Erfahrung ist es schwierig geworden zu behaupten, Programm A ist
besser als Programm B. Und ohne die im RB_2002 Turnier gespielten Partien
qualitativ zu untersuchen, wage ich keine Aussage ausser: Es war einfach ein
Turnier von vielen.
