Member Function Documentation

◆ Accept()

void Accept ( ModelVisitor *const visitor ) const

virtualinherited

Accepts the given model visitor.

Reimplemented in RegularLimit, and OptimizeVar.

Definition at line 2929 of file constraint_solver.cc.

◆ AcceptDelta()

bool AcceptDelta	(	Assignment *	delta,
		Assignment *	deltadelta
	)

virtualinherited

Reimplemented in OptimizeVar.

Definition at line 2923 of file constraint_solver.cc.

◆ AcceptNeighbor()

void AcceptNeighbor ( )

virtualinherited

After accepting a neighbor during local search.

Definition at line 2926 of file constraint_solver.cc.

◆ AcceptSolution()

bool AcceptSolution ( )

virtualinherited

This method is called when a solution is found.

It asserts whether the solution is valid. A value of false indicates that the solution should be discarded.

Reimplemented in OptimizeVar.

Definition at line 2919 of file constraint_solver.cc.

◆ AcceptUncheckedNeighbor()

void AcceptUncheckedNeighbor ( )

virtualinherited

After accepting an unchecked neighbor during local search.

Reimplemented in SearchLog.

Definition at line 2927 of file constraint_solver.cc.

◆ AddTermToClause()

void AddTermToClause	(	SymmetryBreaker *const	visitor,
		IntVar *const	term
	)

inline

Definition at line 5047 of file search.cc.

◆ AfterDecision()

void AfterDecision	(	Decision *const	d,
		bool	apply
	)

virtualinherited

Just after refuting or applying the decision, apply is true after Apply.

This is called only if the Apply() or Refute() methods have not failed.

Definition at line 2914 of file constraint_solver.cc.

◆ ApplyDecision()

void ApplyDecision ( Decision *const d )

virtualinherited

Before applying the decision.

Reimplemented in SearchLog.

Definition at line 2912 of file constraint_solver.cc.

◆ AtSolution()

bool AtSolution ( )

virtualinherited

This method is called when a valid solution is found.

If the return value is true, then search will resume after. If the result is false, then search will stop there.

Reimplemented in SearchLog, ImprovementSearchLimit, and OptimizeVar.

Definition at line 2920 of file constraint_solver.cc.

◆ BeginFail()

void BeginFail ( )

virtualinherited

Just when the failure occurs.

Reimplemented in DemonProfiler, and SearchLog.

Definition at line 2915 of file constraint_solver.cc.

◆ BeginInitialPropagation()

void BeginInitialPropagation ( )

virtualinherited

Before the initial propagation.

Reimplemented in SearchLog.

Definition at line 2917 of file constraint_solver.cc.

inline

Definition at line 5010 of file search.cc.

◆ DebugString()

std::string DebugString ( ) const

inlineoverridevirtual

Reimplemented from BaseObject.

Definition at line 5051 of file search.cc.

◆ EndFail()

void EndFail ( )

virtualinherited

After completing the backtrack.

Definition at line 2916 of file constraint_solver.cc.

		Decision *const	d
	)

inlineoverridevirtual

After calling DecisionBuilder::Next, along with the returned decision.

Reimplemented from SearchMonitor.

Definition at line 4986 of file search.cc.

◆ EnterSearch()

void EnterSearch ( )

virtualinherited

Beginning of the search.

Reimplemented in SearchLog, SearchLimit, OptimizeVar, and SolutionCollector.

Definition at line 2906 of file constraint_solver.cc.

◆ ExitSearch()

void ExitSearch ( )

virtualinherited

End of the search.

Reimplemented in LocalSearchProfiler, SearchLog, and RegularLimit.

Definition at line 2908 of file constraint_solver.cc.

◆ Install()

void Install ( )

virtualinherited

Registers itself on the solver such that it gets notified of the search and propagation events.

Override to incrementally install listeners for specific events.

Reimplemented in LocalSearchProfiler, DemonProfiler, LocalSearchMonitor, PropagationMonitor, ImprovementSearchLimit, RegularLimit, SearchLimit, SolutionCollector, LocalSearchMonitorPrimary, and Trace.

Definition at line 2931 of file constraint_solver.cc.
