InteractiveOptimizer
mip tolerances integrality
Identifier
2010
Description
Specifies the amount by which an integer variable can be different from an integer and still be considered feasible.
A value of zero is permitted, and the optimizer will attempt to meet this tolerance.
However, in some models, computer roundoff may still result in small, nonzero deviations from integrality. If any of these deviations exceed the value of this parameter, or exceed 1e-10 in the case where this parameter has been set to a value less than that, a solution status of CPX_STAT_OPTIMAL_INFEAS
will be returned instead of the usual CPX_STAT_OPTIMAL
.
Values
Any number from 0.0 to 0.5; default: 1e-05.
