ILOG CPLEX .NET Reference Manual

Cplex.BestObjValue Property

Gets a bound on the optimal solution value of the active problem in a MIP. When a model has been solved to optimality, this value matches the optimal solution value within the current MIP gap tolerance. If a MIP optimization is terminated before optimality has been proven, this value is computed for a minimization (maximization) problem as the minimum (maximum) objective function value of all remaining unexplored nodes.
