Description
Sets an upper limit on the value of the objective function in the simplex algorithms. Setting an upper objective function limit causes CPLEX to halt the optimization process when the maximum objective function value limit has been reached. This limit applies only during Phase II of the simplex algorithm in maximization problems.
This parameter is not effective with the conflict refiner nor with FeasOpt. That is, neither of those tools can analyze an infeasibility introduced by this parameter. If you want to analyze such a condition, add an explicit objective constraint, such as obj <= c. to your model instead before you invoke either of those tools.
Values
Any number; default: 1e+75.
