public class GreedySchrimpfFactory
extends java.lang.Object

Factory that creates the VehicleRoutingAlgorithm as proposed by Schrimpf et al., 2000 with the following parameters:

R&R_random (prob=0.5, F=0.5); R&R_radial (prob=0.5, F=0.3); threshold-accepting with exponentialDecayFunction (alpha=0.1, warmup-iterations=100); nuOfIterations=2000
