Member Function Documentation
◆ Accept()
|
virtualinherited |
Accepts the given model visitor.
Reimplemented in OptimizeVar, and RegularLimit.
◆ AcceptDelta()
|
virtualinherited |
Reimplemented in OptimizeVar.
◆ AcceptNeighbor()
|
virtualinherited |
After accepting a neighbor during local search.
◆ 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.
◆ AcceptUncheckedNeighbor()
|
virtualinherited |
After accepting an unchecked neighbor during local search.
Reimplemented in SearchLog.
◆ AfterDecision()
|
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.
◆ ApplyDecision()
|
virtualinherited |
Before applying the decision.
Reimplemented in SearchLog.
◆ 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 OptimizeVar, ImprovementSearchLimit, and SearchLog.

|
pure virtual |
Propagation events.
◆ BeginDemonRun()
|
pure virtual |
◆ BeginFail()

Reimplemented in RegularLimit.
Definition at line 3706 of file constraint_solver.h.
◆ LocalOptimum()
|
virtualinherited |
When a local optimum is reached.
If 'true' is returned, the last solution is discarded and the search proceeds with the next one.
