java - Graph - Non Simple Path , Longest Path - Stack Overflow
Dec 8, 2019 · Your understanding is correct: a non-simple path will always contain a cycle. Take the first instance of the first repeated node on the non-simple path and follow the path until you revisit that …
Why finding the longest path in a graph is NP-hard
The confusion here is that the Longest Path Problem generally asks for the longest simple path, i.e., the longest path without repeated vertices. For this reason, it can be reduced to the Hamiltonian Path …
