Letbe a graph embedded in an orientable surface, possibly with edge weights, and denote bythe length (the number of edges or the sum of the edge weights) of a cyclein. The stretch of a graph embedded on a surface is the minimum ofover all pairs of cyclesandthat cross exactly once. We provide two algorithms to compute the stretch of an embedded graph, each based on a different principle. The first algorithm is based on surgery and computes the stretch in timewith high probability, or in timein the worst case, whereis the genus of the surfaceandis the number of vertices in. The second algorithm is based on using a short homology basis and computes the stretch in time.
