This result partially answers an open question posed by Thorup (2007). It also stays in sharp contrast to a polynomial conditional lower bound for the fully dynamic weighted minimum cut problem. Our algorithm is obtained by combining a sparsification technique of Kawarabayashi and Thorup (2015) or its recent improvement by Henzinger, Rao, and Wang (2017), and an exact incremental algorithm of Henzinger (1997).\r\n\r\nWe also study space-efficient incremental algorithms for the minimum cut problem. Concretely, we show that there exists an O(nlog n/ε2) space Monte Carlo algorithm that can process a stream of edge insertions starting from an empty graph, and with high probability, the algorithm maintains a (1+ε)-approximation to the minimum cut. The algorithm has O((α (n) log3 n)/ε 2) amortized update time and constant query time, where α (n) stands for the inverse of Ackermann function."}],"status":"public","day":"01","quality_controlled":"1","acknowledgement":"We thank the two anonymous reviewers for their suggestions and comments, which improved the\r\nquality of the article.","extern":"1","main_file_link":[{"url":"https://arxiv.org/abs/1611.06500","open_access":"1"}],"volume":14,"external_id":{"arxiv":["1611.06500"]},"article_type":"original"}
