WebNov 4, 2008 · Add a comment. 34. In my opinion, the most understandable algorithm for detecting cycle in a directed graph is the graph-coloring-algorithm. Basically, the graph coloring algorithm walks the graph in a DFS manner (Depth First Search, which means that it explores a path completely before exploring another path). WebApr 7, 2024 · Tarjan’s algorithm now takes the form of a series of DFS invocations: 6. The Complexity Analysis. Tarjan’s algorithm is a modification of the DFS traversal. So, the complexity of the algorithm is linear: , where is the number of vertices and is the number of edges. Please note that to achieve the mentioned complexity, we must use the ...
