Constructor & Destructor Documentation

◆ init()

ortools.constraint_solver.pywrapcp.SearchMonitor.__init__	(		self,
			s )

Definition at line 2474 of file pywrapcp.py.

Member Function Documentation

◆ disown()

ortools.constraint_solver.pywrapcp.SearchMonitor.__disown__ ( self )

Definition at line 2583 of file pywrapcp.py.

◆ repr()

ortools.constraint_solver.pywrapcp.SearchMonitor.__repr__ ( self )

Definition at line 2578 of file pywrapcp.py.

◆ str()

ortools.constraint_solver.pywrapcp.SearchMonitor.__str__ ( self )

Definition at line 2581 of file pywrapcp.py.

◆ AcceptDelta()

ortools.constraint_solver.pywrapcp.SearchMonitor.AcceptDelta	(	self,
		delta,
		deltadelta )

Definition at line 2560 of file pywrapcp.py.

◆ AcceptNeighbor()

ortools.constraint_solver.pywrapcp.SearchMonitor.AcceptNeighbor ( self )

After accepting a neighbor during local search.

Definition at line 2564 of file pywrapcp.py.

◆ AcceptSolution()

ortools.constraint_solver.pywrapcp.SearchMonitor.AcceptSolution ( self )

    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.

Definition at line 2533 of file pywrapcp.py.

◆ AfterDecision()

ortools.constraint_solver.pywrapcp.SearchMonitor.AfterDecision	(	self,
		d,
		apply )

    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 2510 of file pywrapcp.py.

◆ ApplyDecision()

ortools.constraint_solver.pywrapcp.SearchMonitor.ApplyDecision	(		self,
			d )

Before applying the decision.

Definition at line 2502 of file pywrapcp.py.

◆ AtSolution()

ortools.constraint_solver.pywrapcp.SearchMonitor.AtSolution ( self )

    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.

Definition at line 2541 of file pywrapcp.py.

◆ BeginFail()

ortools.constraint_solver.pywrapcp.SearchMonitor.BeginFail ( self )

Just when the failure occurs.

Definition at line 2517 of file pywrapcp.py.

◆ BeginInitialPropagation()

ortools.constraint_solver.pywrapcp.SearchMonitor.BeginInitialPropagation ( self )

Before the initial propagation.

Definition at line 2525 of file pywrapcp.py.

◆ BeginNextDecision()

ortools.constraint_solver.pywrapcp.SearchMonitor.BeginNextDecision	(		self,
			b )

Before calling DecisionBuilder::Next.

Reimplemented in ortools.constraint_solver.pywrapcp.SearchLimit.

Definition at line 2494 of file pywrapcp.py.

◆ EndFail()

ortools.constraint_solver.pywrapcp.SearchMonitor.EndFail ( self )

After completing the backtrack.

Definition at line 2521 of file pywrapcp.py.

◆ EndInitialPropagation()

ortools.constraint_solver.pywrapcp.SearchMonitor.EndInitialPropagation ( self )

After the initial propagation.

Definition at line 2529 of file pywrapcp.py.

◆ EndNextDecision()

ortools.constraint_solver.pywrapcp.SearchMonitor.EndNextDecision	(	self,
		b,
		d )

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

Definition at line 2498 of file pywrapcp.py.

◆ EnterSearch()

ortools.constraint_solver.pywrapcp.SearchMonitor.EnterSearch ( self )

Beginning of the search.

Reimplemented in ortools.constraint_solver.pywrapcp.SearchLimit, and ortools.constraint_solver.pywrapcp.SolutionCollector.

Definition at line 2482 of file pywrapcp.py.

◆ ExitSearch()

ortools.constraint_solver.pywrapcp.SearchMonitor.ExitSearch ( self )

End of the search.

Definition at line 2490 of file pywrapcp.py.

◆ LocalOptimum()

ortools.constraint_solver.pywrapcp.SearchMonitor.LocalOptimum ( self )

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

Definition at line 2553 of file pywrapcp.py.

◆ NoMoreSolutions()

ortools.constraint_solver.pywrapcp.SearchMonitor.NoMoreSolutions ( self )

When the search tree is finished.

Definition at line 2549 of file pywrapcp.py.

◆ ProgressPercent()

ortools.constraint_solver.pywrapcp.SearchMonitor.ProgressPercent ( self )

    Returns a percentage representing the propress of the search before
    reaching limits.

Definition at line 2568 of file pywrapcp.py.

◆ RefuteDecision()

ortools.constraint_solver.pywrapcp.SearchMonitor.RefuteDecision	(		self,
			d )

Before refuting the decision.

Reimplemented in ortools.constraint_solver.pywrapcp.SearchLimit.

Definition at line 2506 of file pywrapcp.py.

◆ RestartSearch()

ortools.constraint_solver.pywrapcp.SearchMonitor.RestartSearch ( self )

Restart the search.

Definition at line 2486 of file pywrapcp.py.

◆ solver()

ortools.constraint_solver.pywrapcp.SearchMonitor.solver ( self )

Definition at line 2575 of file pywrapcp.py.
