Recently three mathematicians at the University of Washington (Nathan Klein, Anna Karlin, Shayan Oveis Gharan) managed to improve on Nicos Christofides' 1976 algorithm in which "round trips that are at most 50% longer than the best round trip". The Klein-Karlin-Gharan algorithm shaves "0.2 billionth of a trillionth of a trillionth of a percent" off the 50% mark.
