Method Details

explore

public ExploreResult<FLPRelocateNeigh.RelocateMove, FLPSolution, FLPInstance> explore(FLPSolution 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<FLPRelocateNeigh.RelocateMove, FLPSolution, FLPInstance>

Parameters:

solution - Solution used to generate the neighborhood

Returns:

Stream with all the available moves in the neighborhood

getRandomMove

public Optional<FLPRelocateNeigh.RelocateMove> getRandomMove(FLPSolution solution)

Description copied from class: RandomizableNeighborhood

Pick a random move within the neighborhood

Specified by:

getRandomMove in class RandomizableNeighborhood<FLPRelocateNeigh.RelocateMove, FLPSolution, FLPInstance>

Parameters:

solution - Solution used to generate the neighborhood

Returns:

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