We analyze a local search algorithm for this problem which uses only the operations of add, delete and swap and prove that any locally optimum solution is no more than 3 times the global optimum. This improves on a result of Chudak and Williamson who proved an approximation ratio of {\$}3+2{\backslash}sqrt{\{}2{\}}{\$} for the same algorithm. We also provide an example which shows that our analysis is tight.", isbn="978-3-642-13036-6" }
