MATLAB: Anyone knows whether is possible to perfome an optimization with Global Search using only integer inputs

Question

I'd like to perform an optimization using Global Search in Matlab but I dont know how to restrict inputs as integer like Intcon in Genetic Algorithm.

[x,fval,exitflag] = ga(fitnessfcn,nvars,A,b,[],[],… lb,ub,nonlcon, IntCon,options)

The idea is to execute another optimization technique with Global Search but limiting inputs only to integer.

Thanks in advance

Answer 1

The answer is no. GlobalSearch uses fmincon as its local optimizer, and there is no way to restrict fmincon to integer values. Sorry.
