Abstract

We give an algorithm for determining the distance between two vertices of the\ncomplex of curves. While there already exist such algorithms, for example by\nLeasure, Shackleton, and Webb, our approach is new, simple, and more effective\nfor all distances accessible by computer. Our method gives a new preferred\nfinite set of geodesics between any two vertices of the complex, called\nefficient geodesics, which are different from the tight geodesics introduced by\nMasur and Minsky.\n
