Network.complement

Network.complement(cls=None)[source]

Generate the complement network of a network.

The complement of a graph G is the graph H with the same vertices but whose edges consists of the edges not present in the graph G 1.

Parameters

network (Network) – A network.

Returns

Network – The complement network.

Examples

>>> import compas
>>> from compas.datastructures import Network
>>> from compas.datastructures import network_complement
>>> network = Network.from_obj(compas.get('lines.obj'))
>>> complement = network_complement(network)
>>> any(complement.has_edge(u, v, directed=False) for u, v in network.edges())
False
