Constructor Details

AcceptNewRemoveFirst

public AcceptNewRemoveFirst(int solutionMemory)

Method Details

acceptSolution

public boolean acceptSolution(Collection<VehicleRoutingProblemSolution> solutions,
 VehicleRoutingProblemSolution newSolution)

Accepts every solution if solution memory allows. If memory occupied, than accepts new solution only if better than the worst in memory. Consequently, the worst solution is removed from solutions, and the new solution added.

Note that this modifies Collection solutions.

Specified by:

acceptSolution in interface SolutionAcceptor

Parameters:

solutions - collection of existing solutions

newSolution - new solution to be evaluated

Returns:

true if solution accepted

toString

public String toString()

Overrides:

toString in class Object
