WebChoose the augmenting path with largest bottleneck value. It’s a fairly easy to show that the maximum-bottleneck (s,t)-path in a directed graph can be computed in O(ElogV)time using a variant of Jarník’s minimum-spanning-tree algorithm, or of Dijkstra’s shortest path algorithm. Simply grow a directed spanning tree T, rooted at s.

The cue problem could be solved with manual Platform assignment but if things got out of phase it could still back up a bit. It does mostly fix the delays.
