New to Analytica 4.3 -- prior to Analytica 4.3, was called LpOpt.
OptObjective(opt)
Returns the value of the objective function at the optimum solution. «opt» is a linear, quadratic or non-linear problem defined from a previous call to DefineOptimization.
If the optimization has not yet been solved, the evaluation of OptObjective will cause it to be solved. If it has already been solved (as a result of OptSolution, OptStatusText, or other similar function being previously evaluated), the result is obtained immediately with no further work. It is always a good idea to check the result of OptStatusNum or OptStatusText, since the returned value is only valid when the solver reports finding an optimal, or likely optimal solution.
