Constructor Detail

FastHypervolumeArchive

public FastHypervolumeArchive(int maxSize,
                              int numberOfObjectives)

Constructor.

Parameters:

maxSize - The maximum size of the archive.

numberOfObjectives - The number of objectives.

Method Detail

add

public boolean add(Solution solution)

Adds a Solution to the archive. If the Solution is dominated by any member of the archive, then it is discarded. If the Solution dominates some members of the archive, these are removed. If the archive is full and the Solution has to be inserted, the solution contributing the least to the HV of the solution set is discarded.

Overrides:

add in class SolutionSet

Parameters:

solution - The Solution

Returns:

true if the Solution has been inserted, false otherwise.

computeHVContribution

public void computeHVContribution()

This method forces to compute the contribution of each solution (required for PAEShv)
