Answering two questions posed by Kannan and Lipton in the 1980s, we show that when V has dimension one, this problem is solvable in polynomial time, and when V has dimension two or three, the problem is in NPRP.","lang":"eng"}],"year":"2016","main_file_link":[{"url":"http://arxiv.org/abs/1303.2981","open_access":"1"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","oa_version":"Preprint","department":[{"_id":"KrCh"}],"status":"public","date_published":"2016-06-01T00:00:00Z","article_number":"23","day":"01","date_created":"2018-12-11T11:51:41Z","publication_status":"published","publication":"Journal of the ACM","citation":{"apa":"Chonev, V.
