Member Function Documentation

◆ Accept()

void operations_research::RoundRobinCompoundObjectiveMonitor::Accept ( ModelVisitor * visitor ) const

inlineoverridevirtual

Accepts the given model visitor.

Todo: (user): properly implement this.

Reimplemented from operations_research::SearchMonitor.

Definition at line 3055 of file search.cc.

◆ AcceptDelta()

bool operations_research::RoundRobinCompoundObjectiveMonitor::AcceptDelta	(	Assignment *	delta,
		Assignment *	deltadelta )

inlineoverridevirtual

Reimplemented from operations_research::SearchMonitor.

Definition at line 3004 of file search.cc.

◆ AcceptNeighbor()

void operations_research::RoundRobinCompoundObjectiveMonitor::AcceptNeighbor ( )

inlineoverridevirtual

After accepting a neighbor during local search.

Reimplemented from operations_research::SearchMonitor.

Definition at line 2994 of file search.cc.

◆ AcceptSolution()

bool operations_research::RoundRobinCompoundObjectiveMonitor::AcceptSolution ( )

inlineoverridevirtual

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 from operations_research::SearchMonitor.

Definition at line 3013 of file search.cc.

◆ ApplyDecision()

void operations_research::RoundRobinCompoundObjectiveMonitor::ApplyDecision ( Decision * d )

inlineoverridevirtual

Before applying the decision.

Reimplemented from operations_research::SearchMonitor.

Definition at line 2991 of file search.cc.

◆ AtSolution()

bool operations_research::RoundRobinCompoundObjectiveMonitor::AtSolution ( )

inlineoverridevirtual

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 from operations_research::SearchMonitor.

Definition at line 2997 of file search.cc.

◆ BeginNextDecision()

void operations_research::RoundRobinCompoundObjectiveMonitor::BeginNextDecision ( DecisionBuilder * b )

inlineoverridevirtual

Before calling DecisionBuilder::Next.

Reimplemented from operations_research::SearchMonitor.

Definition at line 3007 of file search.cc.

◆ BestValue()

int64_t operations_research::RoundRobinCompoundObjectiveMonitor::BestValue ( int index ) const

inlineoverridevirtual

Implements operations_research::BaseObjectiveMonitor.

Definition at line 3048 of file search.cc.

◆ DebugString()

std::string operations_research::RoundRobinCompoundObjectiveMonitor::DebugString ( ) const

inlineoverridevirtual

Reimplemented from operations_research::BaseObject.

Definition at line 3052 of file search.cc.

◆ EnterSearch()

void operations_research::RoundRobinCompoundObjectiveMonitor::EnterSearch ( )

inlineoverridevirtual

Beginning of the search.

-------— Search Monitor -------—

Reimplemented from operations_research::SearchMonitor.

Definition at line 2982 of file search.cc.

◆ LocalOptimum()

bool operations_research::RoundRobinCompoundObjectiveMonitor::LocalOptimum ( )

inlineoverridevirtual

When a local optimum is reached. If 'true' is returned, the last solution is discarded and the search proceeds with the next one.

Reimplemented from operations_research::SearchMonitor.

Definition at line 3016 of file search.cc.

◆ Maximize()

bool operations_research::RoundRobinCompoundObjectiveMonitor::Maximize ( int index ) const

inlineoverridevirtual

Implements operations_research::BaseObjectiveMonitor.

Definition at line 3045 of file search.cc.

◆ MinimizationVar()

IntVar * operations_research::RoundRobinCompoundObjectiveMonitor::MinimizationVar ( int index ) const

inlineoverridevirtual

Implements operations_research::BaseObjectiveMonitor.

Definition at line 3039 of file search.cc.

◆ ObjectiveVar()

IntVar * operations_research::RoundRobinCompoundObjectiveMonitor::ObjectiveVar ( int index ) const

inlineoverridevirtual

Implements operations_research::BaseObjectiveMonitor.

Definition at line 3036 of file search.cc.

◆ RefuteDecision()

void operations_research::RoundRobinCompoundObjectiveMonitor::RefuteDecision ( Decision * d )

inlineoverridevirtual

Before refuting the decision.

Reimplemented from operations_research::SearchMonitor.

Definition at line 3010 of file search.cc.
