WebOct 18, 2010 · 28. This is a reduction from undirected Hamilton Cycle to undirected Hamilton Path. It takes a graph G and returns a graph f ( G) such that G has a Hamilton Cycle iff f ( G) has a Hamilton Path. Given a graph G = ( V, E) we construct a graph f ( G) as follows. Let v ∈ V be a vertex of G, and let v ′, s, t ∉ V. WebMay 1, 2024 · Given an undirected graph G and a designated subset C of G’s nodes, is it possible to convert G to a directed graph by assigning directions to each of its edges so that every node in C has indegree 0 or outdegree 0, and every other node in G has indegree at least 1?

Since back edges are those edges ( u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle.
