org.goplanit.assignment.ltm.sltm.PasFlowShiftOriginBasedDestLabelledExecutor

public class PasFlowShiftOriginBasedDestLabelledExecutor
extends PasFlowShiftExecutor

Functionality to conduct a PAS flow shift by means of the simplest labelling technique possible, where all flow attributed to a destination is labelled uniquely throughout the bush. This is least efficient in terms of memory but conceptually the easiest the understand, implement, and test.
