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.
