In this paper, we have worked on a problem in the domain of graph theory and geometry . Objective of our problem is to find out the shortest path with forbidden pairs in a graphs. Given a graph G=(V, E) and set of pairs P={ai, bi|ai ? V? bi ? V}, we have to find out the shortest path between two given vertices s and t, s. t. ai bi both do not occur on the path for any i. We reduce SAT to this problem and thus claim that this problem is NP-hard.
