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 [[Alexander Szabo#TechnologyCurveRevisted|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''. [[Massachusetts Institute of Technology]], Laboratory of Computer Science, Technical Memo No. 608, [http://supertech.lcs.mit.edu/~heinz/ps/new_exp.ps.gz zipped ps], [http://bitsavers.trailing-edge.com/pdf/mit/lcs/tm/MIT-LCS-TM-608.pdf pdf]</ref>: 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). The experimental data indicated slight [[Depth#DiminishingReturns|diminishing returns]] at longer search times. However, the Szabos simply did not play enough games at long times to draw reliable conclusions.
