Some Reflections of a Keen Modeler David E. Goldberg Illinois Genetic Algorithms Laboratory University of Illinois at Urbana-Champaign Urbana, Illinois 61801 [email_address]
Optimal thinking, when marginal cost of a thought equals marginal benefit to design.
C = B
If cost higher than advance in design, thinking is uneconomic.
Science: model is the end.
Engineering; model is instrumental.
Match model complexity to ends required.

A Spectrum of Models The Modeling Spectrum Low Cost/ High Error High Cost/ Low Error Unarticulated Wisdom Articulated Qualitative Model Dimensional Models Facetwise Models Equations of Motion
Need sophisticated, flexible approach to advance state of the art most quickly.
Still many opportunities for model advance in PMBGA/EDAs.
Mastery of the spectrum of models from qual to quant, from little to equations of motion holds hope for continued vibrancy and creativity of the field.
