GraphDifference

GraphDifference[g1,g2]

gives the graph difference of the graphs g1 and g2.

GraphDifference[{vw,…},…]

uses rules vw to specify the graph g.

Details and Options

  • The graph difference Graph[v1,e1]∖Graph[v2,e2] is given by Graph[v1⋃v2,e1∖ e2].
  • GraphDifference works with undirected graphs, directed graphs, multigraphs, and mixed graphs.

Properties & Relations  (6)

The vertices of the graph difference are the union of the vertices of the graphs:

The edges of the graph difference are the complement of the edges of the graphs:

The graph difference of any graph and itself is an empty graph:

The graph difference of any graph and its CompleteGraph is isomorphic to the complement of the graph:
