In graph theory, a cycle represents a path within the graph where only starting and ending nodes are similar. Furthermore, cycles can be double-connected links between neighboring nodes or self-loops. The cycles detection algorithm implemented within MAGE works on an undirected graph and has no guarantee of node order in the output. The implemented algorithm (Gibb) is described in the 1982 MIT report called "Algorithmic approaches to circuit enumeration problems and applications" 1. The problem is not solvable in polynomial time. It is based on finding all subsets of fundamental cycles which takes about O(2^(|E|-|V|+1)) time where E represents a set of edges and V represents a set of vertices of the given graph.

  • cycle_id ➡ Incremental cycle ID of a certain vertex. There is no guarantee on how nodes are going to be ordered within cycle. The cycle can be represented with a minimum of one ID, where it stands for self-loop.
  • node ➡ Vertex object with all properties which is going to be related to the cycle ID it belongs to.
