Thenearest neighbour algorithmwas one of the firstalgorithmsused to solve thetravelling salesman problemapproximately. In that problem, the salesman starts at a random city and repeatedly visits the nearest city until all have been visited. The algorithm quickly yields a short tour, but usually not the optimal one.
