) Three Japanese authors (Azuma Ohuchi, M. Kurihara and I. Kaji) suggested an improvement for one of Warfield's ISM algorithms in a 1985 paper titled "Efficient Procedure for Transitive Coupling in ISM," IEEE:SMC v15 n3 (426-431). This 3-page manuscript describes the Ohuchi algorithm and reports on a study of the Japanese paper, during which the GMU computer CDC CYBER 830 was used to run comparison tests. The tests confirm that the Japanese algorithm is more efficient than the old one published in Societal Systems, at least under the conditions studied. Note that the Japanese author's name was misspelled in the test report (Ohuchi is believed to be the correct spelling and was used consistently by Warfield in other writings) Warfield says that he himself did not write this test report, but he had directed that the test be made. Warfield's guess is that David Keever, the computer administrator at the Institute, actually wrote the report but we don't know for sure. Warfield had just begun writing his book "A Science of Generic Design" in 1988, and this test was probably performed as a forerunner of the ISM chapters in the book, where the Japanese algorithm is described and endorsed as an improvement over the original one. (It is worth noting that Warfield never intended that the algorithms given in his publications would be optimal. They were in the nature of existence proofs.) Also worth noting: When I asked him about this evaluation document in April 2008, Warfield's recollection was that he had been unable to get needed software from the Japanese, or documents of some sort, to run the test correctly, and that no real evaluation had been done. I told him he could look it up in the Science of Generic Design, to see what was said there. Warfield said did not remember such a test, but it must have happened. He did comment that while he must have accepted the test results as final in 1988, however if Keever was the one asked to do the test he possibly might not have done it, but told Warfield that he did. Warfield just doesn't remember because it was too long ago. And he doesn't have the energy with his broken arm to look it up in ASOGD. In 2008, Warfield says "It is all right, just leave the record as it is." So I did. It would be nice to get this evaluation repeated under rigorous conditions, but probably that will never happen.
