Method Details

acceptSolution

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

Description copied from interface: SolutionAcceptor

Accepts solution or not, and returns true if a new solution has been accepted.

If the solution is accepted, it is added to solutions, i.e. the solutions-collections is modified.

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

getInitialThreshold

public double getInitialThreshold()

getEndThreshold

public double getEndThreshold()

setInitialThreshold

public void setInitialThreshold(double initialThreshold)

Sets initial threshold.

Note that if initial threshold has been set, automatic generation of initial threshold is disabled.

Parameters:

initialThreshold - the initialThreshold to set

setEndThreshold

public void setEndThreshold(double endThreshold)

setMaxIterations

public void setMaxIterations(int maxIteration)

informAlgorithmStarts

public void informAlgorithmStarts(VehicleRoutingProblem problem,
 VehicleRoutingAlgorithm algorithm,
 Collection<VehicleRoutingProblemSolution> solutions)

Specified by:

informAlgorithmStarts in interface AlgorithmStartsListener

informIterationStarts

public void informIterationStarts(int i,
 VehicleRoutingProblem problem,
 Collection<VehicleRoutingProblemSolution> solutions)

Specified by:

informIterationStarts in interface IterationStartsListener
