MixedGraphQ

MixedGraphQ[g]

yields True if the graph g is a mixed graph and False otherwise.

Details

  • A graph is mixed if it has both directed and undirected edges.

Examples

open all close all

Basic Examples  (2)

Test whether a graph is a mixed graph:

Wolfram Language code: Graph[{12, 23, 31}]
Wolfram Language code: MixedGraphQ[%]

MixedGraphQ gives False for inputs that are not graphs with mixed edges:

Wolfram Language code: CompleteGraph[5]
Wolfram Language code: MixedGraphQ[%]

Scope  (6)

MixedGraphQ works with undirected graphs:

Wolfram Language code: MixedGraphQ[[image]]

Directed graphs:

Wolfram Language code: MixedGraphQ[[image]]

Multigraphs:

Wolfram Language code: MixedGraphQ[[image]]

Mixed graphs:

Wolfram Language code: MixedGraphQ[[image]]

MixedGraphQ gives False for expressions that are not graphs:

Wolfram Language code: MixedGraphQ[x]

MixedGraphQ works with large graphs:

Wolfram Language code: g = Graph[Flatten[Table[If[i == j, ij, ij], {i, 1000}, {j, i, 1000}]]];
