The routine CPXgetbestobjval accesses the currently best known bound on the optimal solution value of a MIP model. When a model has been solved to optimality, this value matches the optimal solution value. Otherwise, this value is computed for a minimization (maximization) problem as the minimum (maximum) objective function value of all remaining unexplored nodes.

Example

 status = CPXgetbestobjval (env, lp, &objval);
