Member Function Documentation

void operations_research::SearchLog::EnterSearch

(

)

[virtual]

Beginning of the search.

Search Monitor.

Reimplemented from operations_research::SearchMonitor.

Definition at line 77 of file search.cc.

void operations_research::SearchLog::ExitSearch

(

)

[virtual]

End of the search.

Reimplemented from operations_research::SearchMonitor.

Definition at line 84 of file search.cc.

bool operations_research::SearchLog::AtSolution

(

)

[virtual]

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.

void operations_research::SearchLog::BeginFail

(

)

[virtual]

Just when the failure occurs.

Reimplemented from operations_research::SearchMonitor.

Definition at line 160 of file search.cc.

void operations_research::SearchLog::NoMoreSolutions

(

)

[virtual]

When the search tree is finished.

Reimplemented from operations_research::SearchMonitor.

Definition at line 164 of file search.cc.

void operations_research::SearchLog::ApplyDecision

(

Decision *const

d

)

[virtual]

Before applying the decision.

Reimplemented from operations_research::SearchMonitor.

Definition at line 185 of file search.cc.

void operations_research::SearchLog::RefuteDecision

(

Decision *const

d

)

[virtual]

Before refuting the Decision.

Reimplemented from operations_research::SearchMonitor.

Definition at line 193 of file search.cc.

void operations_research::SearchLog::OutputDecision

)

[virtual]

Before the initial propagation.

Reimplemented from operations_research::SearchMonitor.

Definition at line 234 of file search.cc.

void operations_research::SearchLog::EndInitialPropagation

(

)

[virtual]

After the initial propagation.

Reimplemented from operations_research::SearchMonitor.
