The routine CPXgetbestobjval accesses the currently best known bound on the optimal solution value of the problem at the time the invoking callback is called by an instance of IloCplex while solving a MIP. 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);
