Best algorithm for detecting cycles in a directed graph [closed]
Tarjan’s strongly connected components algorithm has O(|E| + |V|) time complexity. For other algorithms, see Strongly connected components on Wikipedia.

That heavily depends on the structure of the search tree and the number and location of solutions (aka searched-for items). If you know a solution is not far from the root of the tree, a breadth first search (BFS) might be better. If the tree is very deep and solutions are rare, depth first search … Read more
