Abstract(in English) We consider the problem of finding the minimum time at which all supplies on a dynamic flow network can reach the demand point, which we term Quickest Evacuation Time. Polynomial-time algorithms are known for general networks, but they use the submodular function minimization algorithm as a subroutine, and their computational complexity is a high-order polynomial. In this paper, we propose an efficient polynomial time algorithm for bidirected grid networks with uniform edge capacity and uniform transit time, which does not use a submodular function minimization algorithm.
