◆ SeparateFractionalSolution()

std::vector< CallbackRangeConstraint > operations_research::ScipConstraintHandlerForMPCallback::SeparateFractionalSolution ( const ScipConstraintHandlerContext & context,
const EmptyStruct & constraint )
overridevirtual

Unless SeparateIntegerSolution() below is overridden, this must find a violated lazy constraint if one exists when given an integral solution.

Implements operations_research::ScipConstraintHandler< EmptyStruct >.

◆ SeparateIntegerSolution()

std::vector< CallbackRangeConstraint > operations_research::ScipConstraintHandlerForMPCallback::SeparateIntegerSolution ( const ScipConstraintHandlerContext & context,
const EmptyStruct & constraint )
overridevirtual

This MUST find a violated lazy constraint if one exists. All constraints returned must have is_cut as false.

Reimplemented from operations_research::ScipConstraintHandler< EmptyStruct >.
