Abstract: In this talk, I will describe recent work in which we obtain a 3/2-epsilon approximation algorithm for metric TSP, for some epsilon>10^{-36}. This slightly improves over the classical 3/2 approximation algorithm due to Christofides [1976] and Serdyukov [1978]. The talk will focus on giving an overview of the key ideas involved. This is joint work with Anna Karlin and Shayan Oveis Gharan.
