cugraph.tree.minimum_spanning_tree.minimum_spanning_tree

cugraph.tree.minimum_spanning_tree.minimum_spanning_tree(G, weight=None, algorithm='boruvka', ignore_nan=False)

Returns a minimum spanning tree (MST) or forest (MSF) on an undirected graph

Parameters:

GcuGraph.Graph or networkx.Graph

cuGraph graph descriptor with connectivity information.

weightstring

default to the weights in the graph, if the graph edges do not have a weight attribute a default weight of 1 will be used.

algorithmstring

Default to ‘boruvka’. The parallel algorithm to use when finding a minimum spanning tree.

ignore_nanbool

Default to False

Returns:

G_mstcuGraph.Graph or networkx.Graph

A graph descriptor with a minimum spanning tree or forest. The networkx graph will not have all attributes copied over

Examples

>>> from cugraph.datasets import netscience
>>> G = netscience.get_graph(download=True)
>>> G_mst = cugraph.minimum_spanning_tree(G)
