reevaluates the objective function values for a solution population of a genetic algorithm optimization
The GAREEVAL call computes the objective values for a solution population of a genetic algorithm optimization. Since the GAINIT call and the GAREGEN call also evaluate the objective function values, it is usually not necessary to call GAREEVAL. It is provided to handle the situation of a user modifying an objective function independently - for example, adjusting a global variable to relax or tighten a penalty constraint. In such a case, GAREEVAL should be called before the next GAREGEN call.
