Longest simple path in a directed acyclic graph Suppose that we are given a directed acyclic graph G D .V; E/ with realvalued edge weights and two distinguished vertices s and t. Describe a dynamicprogramming approach for finding a longest weighted simple path from s to t. What does the subproblem graph look like? What is the efficiency of your algorithm?
