(1) Our deterministic algorithm takes O (W 2 log W /ε3) worst-case update time, which is O (1) if both W and ε are constants. (2) Our randomized (Monte-Carlo style) algorithm works with high probability and runs in worst-case O (log W /ε4) update time if W = O ((m∗)1/6/log2/3 n), where m∗ is the minimum number of edges in the graph throughout all the updates. It works even against an adaptive adversary. We complement our algorithmic results with two cell-probe lower bounds for dynamically maintaining an approximation of the weight of an MSF of a graph.","lang":"eng"}],"publisher":"Elsevier","type":"journal_article","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"01","main_file_link":[{"url":"https://arxiv.org/abs/2011.00977","open_access":"1"}]}
