Method Details

isCapacitatedSpanningTree

boolean isCapacitatedSpanningTree(Graph<V,E> graph,
 V root,
 double capacity,
 Map<V,Double> demands)

Tests whether cmst is a CMST on graph with root root, capacity capacity and demand function demands.

Parameters:

graph - the graph

root - the expected root of cmst

capacity - the expected capacity of cmst

demands - the demand function

Returns:

whether cmst is a CMST

getLabels

Map<V,Integer> getLabels()

Return the set of labels of the underlying partition of the capacitated spanning tree. The labels are a key to the vertex sets of the partition.

Returns:

the label set of the capacitated spanning tree.

getPartition

Map<Integer,Pair<Set<V>,Double>> getPartition()

Return the label-to-partition map of the underlying partition of capacitated spanning tree.

Returns:

map from labels to the subsets of the partition of the capacitated spanning tree.
