AndrewC, I should not have done this, but my desire to defend those in my own profession is so great that I went and answered your challenge anyway (I pulled it off using my university library privileges). The 9-transistor cubic function generator, results and all, are all right here: Automatic Synthesis Using Genetic Programming of Both the Topology and Sizing for Five Post-2000 Patented Analog and Mixed Analog-Digital Circuits. ...as we now start the countdown to see how quickly Andrew posts his *next* non sequitur explanation/excuse for a) why he need not deal squarely with the issues raised until we jump through 14 more hoops he sets out, or b) why the whole thing is easily dismissed (in Andrew's mind), e.g. "but they didn't use *cheese*, did they? Huh? Huh?!?"
