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