FractionalSolutionFeasible()

template<typename Constraint >

virtual bool operations_research::ScipConstraintHandler< Constraint >::FractionalSolutionFeasible ( const ScipConstraintHandlerContext & context, const Constraint & constraint )

inlinevirtual

Returns true if no constraints are violated.

Definition at line 139 of file scip_callback.h.

IntegerSolutionFeasible()

template<typename Constraint >

virtual bool operations_research::ScipConstraintHandler< Constraint >::IntegerSolutionFeasible ( const ScipConstraintHandlerContext & context, const Constraint & constraint )

inlinevirtual

This MUST find a violated constraint if one exists.

Definition at line 146 of file scip_callback.h.

SeparateFractionalSolution()

template<typename Constraint >

virtual std::vector< CallbackRangeConstraint > operations_research::ScipConstraintHandler< Constraint >::SeparateFractionalSolution ( const ScipConstraintHandlerContext & context, const Constraint & constraint )

pure virtual

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

Implemented in operations_research::ScipConstraintHandlerForMPCallback.

SeparateIntegerSolution()

template<typename Constraint >

virtual std::vector< CallbackRangeConstraint > operations_research::ScipConstraintHandler< Constraint >::SeparateIntegerSolution ( const ScipConstraintHandlerContext & context, const Constraint & constraint )

inlinevirtual

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

Reimplemented in operations_research::ScipConstraintHandlerForMPCallback.
