Description
Sets the upper cutoff tolerance. When the problem is a minimization problem, CPLEX cuts off any nodes that have an objective value at or above the upper cutoff value . When a mixed integer optimization problem is continued, the smaller of these values and the updated cutoff found during optimization are used during the next mixed integer optimization.
A too-restrictive value for the upper cutoff parameter may result in no integer solutions being found.
Values
Any number; default: 1e+75.
