Is there a reason you are trying to express the values in binary as opposed to just placing integer constraints with bounds? Direct link to this answer: If the user is using gatool then we need to know which release the user is using, as it must be a fairly old release. I would like to use gatool to optimize a discrete function whose analytical expression is not known, but whose values in some given points can be computed by means of a script.

You can apply the genetic algorithm to solve problems that are not well suited for standard optimization algorithms, including problems in which the objective function is discontinuous, nondifferentiable, stochastic, or highly nonlinear.
This is machine translation Translated by. How can I declare matllab input of Genetic Algorithm such as population size, number of variables changing constantly with next iterations?
