Method Details

computePartition

public void computePartition()

Computes a partition of the associated hypergraph. The partition is computed only once. If you want to improve the current partition, use improvePartition(int) instead.

See Also:

• improvePartition(int)

improvePartition

public void improvePartition(int nbIterations)

Improves the last partition that has been computed by this partitioner. The method computePartition() must have been invoked before invoking this method.

Parameters:

nbIterations - The number of iterations to perform for improving the partition.

• computePartition()

getLastPartition

public int[] getLastPartition()

Gives the last partition that has been computed by this partitioner.

Returns:

The last computed partition.

getLastObjectiveValue

public int getLastObjectiveValue()

Gives the value of the objective function on the last computed partition.

Returns:

The last value of the objective function.
