Matlab Multi-optimization Toolbox

Hi,

I have a very basic question about Matlab Multi-optimization Toolbox. Does Matlab use NSGA II (Non-dominated Sorting Genetic Algorithm II) in this Toolbox? I know how to do a multi-objective optimization using this Toolbox but I am curious to know the exact method which Matlab implements.

Best, Hami

Not exactly. See

http://www.mathworks.com/help/optim/ug/fgoalattain.html#moreabout

http://www.mathworks.com/help/optim/ug/fminimax.html#moreabout

Neither of the above two use anything related to NSGA-II. But

http://www.mathworks.com/help/gads/gamultiobj.html#moreabout

"gamultiobj uses a controlled elitist genetic algorithm (a variant of NSGA-II [1]). An elitist GA always favors individuals with better fitness value (rank). A controlled elitist GA also favors individuals that can help increase the diversity of the population even if they have a lower fitness value"

Hi,

Thanks for the concise answer. Actually I wanted to know if "gamultiobj" uses NSGA-II or not. So, the second part of your answer is exactly what I needed to know.
