Center node: "circulation control for faster minimum cost flow in unit capacity graphs"
  Abstract: We present an $m^{11/8+o(1)} \log W$-time algorithm for solving the minimum cost flow problem in graphs with unit capacity, where $W$ is the absolute maximum weight of an edge in the graph. For sparse graphs, this improves over the best known running time for this problem and, by well-known reductions, also implies improved running times for the shortest path problem with negative weights, minimum cost bipartite $\boldsymbol{\mathit{b}}$-matching when $\|\boldsymbol{\mathit{b}}\|_1 = O(m)$, and recovers the running time of the currently fastest algorithm for maximum flow in graphs with unit capacities (Liu-Sidford). #R##N#Our algorithm relies on developing an interior point method--based framework which acts on the space of circulations in the underlying graph. From the combinatorial point of view, this framework can be viewed as iteratively improving the cost of a suboptimal solution by pushing flow around circulations. These circulations are derived by computing a regularized version of the standard Newton step, which can be done efficiently due to recent developments on computing $\ell_p$-norm minimizing flows (Kyng-Peng-Sachdeva-Wang). We obtain our faster algorithm by combining this approach with a customized preconditioning method, which aims to ensure that the graph on which these circulations are computed has sufficiently large conductance.
