Detailed Description

GlobalVehicleBreaksConstraint ensures breaks constraints are enforced on
all vehicles in the dimension passed to its constructor.
It is intended to be used for dimensions representing time.
A break constraint ensures break intervals fit on the route of a vehicle.
For a given vehicle, it forces break intervals to be disjoint from visit
intervals, where visit intervals start at CumulVar(node) and last for
node_visit_transit[node]. Moreover, it ensures that there is enough time
between two consecutive nodes of a route to do transit and vehicle breaks,
i.e. if Next(nodeA) = nodeB, CumulVar(nodeA) = tA and CumulVar(nodeB) = tB,
then SlackVar(nodeA) >= sum_{breaks [tA, tB)} duration(break).

Constructor & Destructor Documentation

__init__()

ortools.constraint_solver.pywrapcp.GlobalVehicleBreaksConstraint.__init__	(		self,
			dimension )

Reimplemented from ortools.constraint_solver.pywrapcp.Constraint.

Definition at line 6000 of file pywrapcp.py.

Member Function Documentation

DebugString()

ortools.constraint_solver.pywrapcp.GlobalVehicleBreaksConstraint.DebugString

(

self

)

Reimplemented from ortools.constraint_solver.pywrapcp.Constraint.

Definition at line 6003 of file pywrapcp.py.

InitialPropagateWrapper()

ortools.constraint_solver.pywrapcp.GlobalVehicleBreaksConstraint.InitialPropagateWrapper

(

self

)

    This method performs the initial propagation of the
    constraint. It is called just after the post.

Reimplemented from ortools.constraint_solver.pywrapcp.Constraint.

Definition at line 6009 of file pywrapcp.py.

Post()

ortools.constraint_solver.pywrapcp.GlobalVehicleBreaksConstraint.Post

(

self

)

    This method is called when the constraint is processed by the
    solver. Its main usage is to attach demons to variables.

Reimplemented from ortools.constraint_solver.pywrapcp.Constraint.

Definition at line 6006 of file pywrapcp.py.
