Method Detail

initStrategy

public void initStrategy(ThreadContext context)

Description copied from interface: IStrategy

Initializes the strategy with a specific ThreadContext.

Specified by:

initStrategy in interface IStrategy

Parameters:

context - The context.

explore

public void explore()

Description copied from interface: IStrategy

This method explores the design space as the implementation specifies. It will be called only once, hence the exploration loop is run by the implementation. The termination condition is also specified by the implementation and when it returns the exploration thread will be disposed.

Specified by:

explore in interface IStrategy

setPopulationSize

public void setPopulationSize(int populationSize)

Description copied from interface: IInitialPopulationSelector

Sets the populations size in the initialization phase. The engine expects this amount of child from the implementation of this interface via the IStoreChild implementation.

Specified by:

setPopulationSize in interface IInitialPopulationSelector

Parameters:

populationSize - Expected number of children.

interruptStrategy

public void interruptStrategy()

Description copied from interface: IStrategy

The implementation of this interface should be ready to be interrupted. If this method is called, the IStrategy.explore() method should return ASAP. This method is also called by the SolutionStore class if enough solutions are found.

Specified by:

interruptStrategy in interface IStrategy

getInitialPopulation

public java.util.Set<TrajectoryFitness> getInitialPopulation()

Specified by:

getInitialPopulation in interface IInitialPopulationSelector
