VertexWeightedGraphQ[g]

yields True if the graph g is a vertex-weighted graph, and False otherwise.

Details

VertexWeightedGraphQ will give True if there is an explicit VertexWeight property defined.

Basic Examples (1)

Test whether a graph is a vertex-weighted graph:

Scope (7)

VertexWeightedGraphQ works with undirected graphs:

Directed graphs:

Weighted graphs:

Multigraphs:

Mixed graphs:

VertexWeightedGraphQ gives False for anything that is not a vertex-weighted graph:

VertexWeightedGraphQ works with large graphs:

Properties & Relations (2)

The vertex-weighted graph is always a weighted graph:

The weighted graph is not always a vertex-weighted graph:

Possible Issues (1)

VertexWeightedGraphQ gives False for non-explicit graphs:
