gets current solution objective function values for a genetic algorithm optimization
The GAGETVAL call is used to retrieve objective function values of the current solution population. If the elite parameter of the GASETSEL call is nonzero, then the first elite members of the population have the most optimal objective function values of the population, and those elite members are sorted in ascending order of objective function value for a minimization problem, or in descending order for a maximization problem.
See the GASETUP function for an example.
