更多信息和选项
- ToOrderedPairs functionality is now available in the built-in Wolfram Language function EdgeList.
- To use ToOrderedPairs, you first need to load the Combinatorica Package using Needs["Combinatorica`"].
- If
is undirected each edge is interpreted as two ordered pairs. - An option called Type that takes on values Simple or All can be used to affect the constructed representation.
- Type->Simple forces the removal of multiple edges and self-loops. Type->All keeps all information and is the default option.
