WeightedGraphQ

WeightedGraphQ[g]

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

Details

  • WeightedGraphQ will give True if there is an explicit VertexWeight or EdgeWeight property defined.
  • In cases where a weighted graph is expected, the default vertex and edge weights are taken to be 1.
  • Weights are often taken to mean cost, capacity, etc.
