Member Function Documentation

AcceptUncheckedNeighbor()

void com.google.ortools.constraintsolver.SearchLog.AcceptUncheckedNeighbor

(

)

After accepting an unchecked neighbor during local search.

Reimplemented from com.google.ortools.constraintsolver.SearchMonitor.

Definition at line 83 of file SearchLog.java.

applyDecision()

void com.google.ortools.constraintsolver.SearchLog.applyDecision

(

Decision

d

)

(

)

Just when the failure occurs.

Reimplemented from com.google.ortools.constraintsolver.SearchMonitor.

Definition at line 75 of file SearchLog.java.

beginInitialPropagation()

void com.google.ortools.constraintsolver.SearchLog.beginInitialPropagation

(

)

Before the initial propagation.

Reimplemented from com.google.ortools.constraintsolver.SearchMonitor.

endInitialPropagation()

void com.google.ortools.constraintsolver.SearchLog.endInitialPropagation

(

)

After the initial propagation.

Reimplemented from com.google.ortools.constraintsolver.SearchMonitor.
