Cumulative

public Cumulative(CPSeqVar seqVar,
 int[] starts,
 int[] ends,
 int[] load,
 int capacity)

Gives a maximum capacity for a resource over a sequence. A set of activity (i.e. a start and corresponding ending node for an activity) can consume the resource. The resource consumption can never exceed the maximum capacity of the resource.

Parameters:

seqVar - sequence over which the constraint is applied.

starts - start of the activities.

ends - corresponding end of each activity. ends[i] is the end activity of i, beginning at starts[i].

load - consumption of each activity.

capacity - maximum capacity for the resource.
