  Abstract: Recently we presented the first algorithm for maintaining the set of nodes reachable from a source node in a directed graph that is modified by edge deletions with \(o(mn)\) total update time, where \(m\) is the number of edges and \(n\) is the number of nodes in the graph [Henzinger et al. STOC 2014]. The algorithm is a combination of several different algorithms, each for a different \(m\) vs. \(n\) trade-off. For the case of \(m = \varTheta (n^{1.5})\) the running time is \(O(n^{2.47})\), just barely below \(mn = \varTheta (n^{2.5})\). In this paper we simplify the previous algorithm using new algorithmic ideas and achieve an improved running time of \(\tilde{O}(\min ( m^{7/6} n^{2/3}, m^{3/4} n^{5/4 + o(1)}, m^{2/3} n^{4/3+o(1)} + m^{3/7} n^{12/7+o(1)}))\). This gives, e.g., \(O(n^{2.36})\) for the notorious case \(m = \varTheta (n^{1.5})\). We obtain the same upper bounds for the problem of maintaining the strongly connected components of a directed graph undergoing edge deletions. Our algorithms are correct with high probabililty against an oblivious adversary.
