Class jsprit.core.algorithm.VehicleRoutingAlgorithm

Examples of jsprit.core.algorithm.VehicleRoutingAlgorithm.searchSolutions()

jsprit.core.algorithm.VehicleRoutingAlgorithm.searchSolutions()
Runs the vehicle routing algorithm and returns a number of generated solutions.
The algorithm runs as long as it is specified in nuOfIterations and prematureBreak. In each iteration it selects a searchStrategy according to searchStrategyManager and runs the strategy to improve solutions.
Note that clients are allowed to observe/listen the algorithm. See {@link VehicleRoutingAlgorithmListener} and its according listeners. @return Collection the solutions @see {@link SearchStrategyManager}, {@link VehicleRoutingAlgorithmListener}, {@link AlgorithmStartsListener}, {@link AlgorithmEndsListener}, {@link IterationStartsListener}, {@link IterationEndsListener}
