FindCycle

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

FindCycle[g]

finds a list of vertices that define a cycle in graph g.

Details and Options

FindCycle functionality is now available in the built-in Wolfram Language function FindCycle.
To use FindCycle, you first need to load the Combinatorica Package using Needs["Combinatorica`"].

Wolfram Language code: Needs["Combinatorica`"]

Wolfram Language code: g = FromUnorderedPairs[{{1, 2}, {2, 3}, {3, 4}, {4, 5}, {1, 5}, {1, 6}}];

Wolfram Language code: ShowGraph[g]

Wolfram Language code: FindCycle[g]

This function has been superseded by FindCycle in the Mathematica kernel:

Wolfram Language code: g = Graph[{12, 15, 23, 34, 45, 16}]

Wolfram Language code: FindCycle[g]
