Analysis. Assumption: capacities are integer-valued. Finding a flow path takes Θ(n + m) time. We send at least 1 unit of flow through the path If the max-flow is f⋆, the time complexity is O((n + m)f⋆) “Bad” in that it depends on the output of the algorithm. Nonetheless, easy to code and works well in practice.
