run

public SearchStrategy.DiscoveredSolution run(VehicleRoutingProblem vrp,
                                             java.util.Collection<VehicleRoutingProblemSolution> solutions)

Runs the search-strategy and its according modules, and returns DiscoveredSolution.

This involves three basic steps: 1) Selecting a solution from solutions (input parameter) according to SolutionSelector, 2) running the modules (SearchStrategyModule) on the selectedSolution and 3) accepting the new solution according to SolutionAcceptor.

Note that after 1) the selected solution is copied, thus the original solution is not modified.

Note also that 3) modifies the input parameter solutions by adding, removing, replacing the existing solutions or whatever is defined in the solutionAcceptor.

Parameters:

vrp -

solutions - which will be modified

Returns:

discoveredSolutin
