Constructor Details

CapacitatedSpanningTreeImpl

public CapacitatedSpanningTreeImpl(Map<V,Integer> labels,
 Map<Integer, Pair<Set<V>,Double>> partition,
 Set<E> edges,
 double weight)

Construct a new capacitated spanning tree.

Parameters:

labels - the labelling of the vertices marking their subset membership in the partition

partition - the implicitly defined partition of the vertices in the capacitated spanning tree

edges - the edge set of the capacitated spanning tree

weight - the weight of the capacitated spanning tree, i.e. the sum of all edge weights

Method Details

isCapacitatedSpanningTree

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

Description copied from interface: CapacitatedSpanningTreeAlgorithm.CapacitatedSpanningTree

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

Specified by:

isCapacitatedSpanningTree in interface CapacitatedSpanningTreeAlgorithm.CapacitatedSpanningTree<V,E>

Parameters:

graph - the graph

root - the expected root of cmst

Specified by:

getPartition in interface CapacitatedSpanningTreeAlgorithm.CapacitatedSpanningTree<V,E>

Returns:

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

getWeight

public double getWeight()

Description copied from interface: SpanningTreeAlgorithm.SpanningTree

Returns the weight of the spanning tree.
