Letters to the Editor
Varol Akman, in his letter (AI Magazine, Spring 1990) criticizing QSIM, quotes both me and Janowski, accurately I believe, describing various limitations of QSIM. At the risk of being scolded again for "employing universal truths and unarguable facts" in support of my position, I must point out that it is the responsibility of a scientist or engineer to document clearly the known limitations of any method he develops and publishes. In addition to truth in packaging, a clear and unblinking examination of the limitations of one's own work is an invaluable guide to further research.
