Details and Options
- 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.
