Fred A while back Tomasz commented about "non continous parameter spaces". Doesn't the use of on/off variables introduce discontinuities in the solution which will present problems when using IO, CMAE, PSO types of optimizers? I appreciate your comments - thanks Larry
"CMAE, PSO and most other non-exhaustive methods are best for continuous parameter spaces. Discrete spaces where adjacent param values result in wild changes in fitness tend to be very difficult to optimize in "intelligent" manner.
