=The Technology Curve=
As published in their 1988 [[ICGA Journal|ICCA Journal]] paper <ref>[[Alexander Szabo]], [[Barbara Szabo]] ('''1988'''). ''The Technology Curve Revisited''. [[ICGA Journal#11_1|ICCA Journal]], Vol. 11, No. 1]]</ref>, Alex and Barbara Szabo revisited the '''Technology Curve''' by playing 6882 games between copies of TechMate set at different time rates, with the conclusion that the advantage of improved technology rapidly decreases when machines and algorithms become more powerful. [[Ernst A. Heinz]] in his self-play memo on the experiment of the Szabos <ref>[[Ernst A. Heinz]] ('''2000'''). ''A New Self-Play Experiment in Computer Chess''.

The Szabos determined the technology curve of their chess program TechMate that self-played 6,882 games on two Atari ST computers. The number of games per match between longer and shorter searching versions of the program varied strongly from a minimum of 32 to a maximum of 1367. The gain in playing strength averaged at 156 rating points per doubling of available search time (computing power).
