SetEdgeWeights

As of Version 10, most of the functionality of the Combinatorica package is built into the Wolfram System. »

SetEdgeWeights[g]

assigns random real weights in the range [0,1] to edges in g.

SetEdgeWeights[g,e]

assigns edge weights to the edges in the edge list e.

SetEdgeWeights[g,w]

assigns the weights in the weight list w to the edges of g.

SetEdgeWeights[g,e,w]

assigns the weights in the weight list w to the edges in edge list e.

SetEdgeWeights functionality is now available in the built-in Wolfram Language function EdgeWeight.
To use SetEdgeWeights, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
SetEdgeWeights accepts options WeightingFunction and WeightRange. The default value for WeightingFunction is Random, and the default value for WeightRange is [0,1].
WeightingFunction can take values Random, RandomInteger, Euclidean, or LNorm[n] for non-negative n, or any pure function that takes two arguments, each argument having the form {Integer,{Number,Number}}.
WeightRange can be an integer range or a real range.
