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.  Best regards, Tomasz Janeczko
