java.lang.Object
org.vanted.plugins.layout.multilevelframework.RandomMerger
All Implemented Interfaces:
Describable, Merger, Parameterizable
public class RandomMerger
extends Object
implements Merger
Merger that randomly merges edges. Note that the default setting is not to merge completely randomly. Starting from the second level, the RandomMerger will prefer merging MergedNodes with low weight. This can be changed through the setting useWeights.

    • buildCoarseningLevels

      public void buildCoarseningLevels​(MultilevelGraph multilevelGraph)
      Builds the coarsening levels for the graph depending on parameters. The parameters coarseningFactor, minNumberOfNodesPerLevel, maxNumberOfIterations, useWeights, considerEdgeWeights affect the coarsening process. Consult the comments above their declaration for more information.
      Specified by:
      buildCoarseningLevels in interface Merger
      Parameters:
      multilevelGraph - The multilevelGraph which the coarsening is performed on. The MultilevelGraph that contains the original graph.
