StageEarliestStart	Interface for setting the earliest start time of a stage in IterativePlanner.

Class Summary

Class	Description
AlignedPlannerWithGreedy	A planning algorithm that first runs LowCostAligned, and if it fails runs Greedy.
GreedyReservationAgent	This Agent employs a simple greedy placement strategy, placing the various stages of a ReservationDefinition from the deadline moving backward towards the arrival.
IterativePlanner	A planning algorithm consisting of two main phases.
IterativePlanner.StageProvider	Helper class that provide a list of ReservationRequests and iterates forward or backward depending whether we are allocating left-to-right or right-to-left.
PlanningAlgorithm	An abstract class that follows the general behavior of planning algorithms.
SimpleCapacityReplanner	This (re)planner scan a period of time from now to a maximum time window (or the end of the last session, whichever comes first) checking the overall capacity is not violated.
StageAllocatorGreedy	Computes the stage allocation according to the greedy allocation rule.
StageAllocatorGreedyRLE	Computes the stage allocation according to the greedy allocation rule.
StageAllocatorLowCostAligned	A stage allocator that iteratively allocates containers in the StageAllocatorLowCostAligned.DurationInterval with lowest overall cost.
StageAllocatorLowCostAligned.DurationInterval	An inner class that represents an interval, typically of length duration.
StageEarliestStartByDemand	Sets the earliest start time of a stage proportional to the job weight.
StageEarliestStartByJobArrival	Sets the earliest start time of a stage as the job arrival time.
TryManyReservationAgents	A planning algorithm that invokes several other planning algorithms according to a given order.
