Graph Shortest Path Problem

Graph Shortest Path Problem Given an undirected weighted graph G (V, E)

Given an undirected weighted graph G (V, E) with non-negative edge weights, and two vertices s,t ? V, let G, be G, but where every edge has its weight increased by 1. Prove that G and G' have the same set of shortest paths from s to t, or provide a counterexample. (*x)
