GraphComplement

GraphComplement[g]

gives the graph complement of the graph g.

GraphComplement[{vw,…}]

uses rules vw to specify the graph g.

Details and Options

  • GraphComplement is also known as edge-complementary graph.
  • The graph complement has the same vertices and edges defined by two vertices being adjacent only if they are not adjacent in g.
  • GraphComplement works with undirected graphs, directed graphs, multigraphs, and mixed graphs.

Properties & Relations  (7)

The complement of a CompleteGraph is an edgeless graph:

The complement of the complement is the original graph (for simple graphs):

The complement of the graph can be obtained from its adjacency matrix:

An independent vertex set of the graph is a clique of its complement graph:

The complement of the line graph of is a Petersen graph:

The graph union of any simple graph and its complement is a complete graph:

The graph intersection of any graph and its complement is an empty graph:
