[[David Levy]], who was tournament director at the [[First GI Computer Chess Tournament]] in [https://en.wikipedia.org/wiki/Dortmund Dortmund], was indebted to Helmut Richter of [https://en.wikipedia.org/wiki/Hamburg Hamburg] for an accurate description of what [[Donald Michie]] called "swap-off". This is described incorrectly on pages 45-47 of ''Chess and Computers'' <ref>[[David Levy]] ('''1976'''). ''Chess and Computers''. Batsford, ISBN 0-7134-3178-4</ref>, the errors having been copied over from Michies's original article on the subject, published in 1966 <ref>[[Donald Michie]] ('''1966'''). ''Game Playing and Game Learning Automata.'' Advances in Programming and Non-Numerical Computation, [https://en.wikipedia.org/wiki/Leslie_Fox Leslie Fox] (ed.), pp. 183-200. Oxford, Pergamon. » Includes Appendix: ''Rules of SOMAC'' by [[John Maynard Smith]]</ref>. Levy gives Richter's description of as Swap-off algorithm what is today usually referred as [[Static Exchange Evaluation|SEE]] in the May 1970 issue of [[Personal Computer World]] <ref>[[David Levy]] ('''1979'''). ''Chess Programming - Before You Begin''. [[Personal Computer World]], May 1979</ref>.<br />
