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

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

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

Is there any way to make the result variable x in either 0 or 1 in global search?

You can make two runs - one with x=0 and one with x=1 - and see which gives the better result.
