Method Details

explore

public ExploreResult<M,S,I> explore(S solution)

Description copied from class: Neighborhood

Build an exhaustive stream that allows iterating the whole neighborhood Using a stream is more efficient that a list as moves are only generated if they are needed

Specified by:

explore in class Neighborhood<M extends Move<S,I>,S extends Solution<S,I>,I extends Instance>

Parameters:

solution - Solution used to generate the neighborhood

Returns:

Stream with all the available moves in the neighborhood

toString

public String toString()

Description copied from class: Neighborhood

Overrides:

toString in class Neighborhood<M extends Move<S,I>,S extends Solution<S,I>,I extends Instance>

getRandomMove

public Optional<M> getRandomMove(S solution)

Description copied from class: RandomizableNeighborhood

Pick a random move within the neighborhood

Specified by:

getRandomMove in class RandomizableNeighborhood<M extends Move<S,I>,S extends Solution<S,I>,I extends Instance>

Parameters:

solution - Solution used to generate the neighborhood

Returns:

a random move, if there is at least one valid move
