WebDerivative-free optimization (sometimes referred to as blackbox optimization ), is a discipline in mathematical optimization that does not use derivative information in the classical sense to find optimal solutions: Sometimes information about the derivative of the objective function f is unavailable, unreliable or impractical to obtain. WebIf we use a derivative-free optimization algorithm below, then nargout will always be 1 and the gradient need never be computed. Our constraint function looks similar, except that it is parameterized by the coefficients a and b. We can just add these on as extra parameters, in a file myconstraint.m:
