Incremental Cycle Detection via Dynamic Minimum Cost Flow

In this talk, I will discuss a new almost-linear time algorithm for maintaining a minimum cost flow on a dynamic graph undergoing edge insertions. This result settles the time complexity of many basic problems on such incremental graphs via simple reductions, including the detection of an occurrence of a directed cycle and the approximate maintenance of st-distances. This talk is based on joint work with Li Chen, Rasmus Kyng, Yang P. Liu, and Maximilian Probst Gutenberg.
