Flow Network Tutorials (With Ford-Fulkerson Algorithm)


Updated July 2026: Flow Networks & Ford-Fulkerson — refreshed for clarity, runnable examples, and current best practices.

A flow network is a directed graph where each edge has a capacity, and the Ford-Fulkerson algorithm computes the maximum flow from a source to a sink. These tutorials walk through the theory and implementation step by step.

What you’ll learn in Flow Networks

  • Flow networks, capacities, sources, sinks, and the value of a flow
  • The Ford-Fulkerson method and augmenting paths on the residual graph
  • Max-flow/min-cut theorem and why it matters
  • The Edmonds-Karp refinement and its complexity
