This study introduces and validates the maximum flow problem to analyze the inhomogeneous critical current (I_c) distribution in superconducting YBa₂Cu₃O_7-y thin films. A sample with a network structure was prepared, and I_c was measured by cutting off a part of the pathway, the results were compared with calculations using the maximum flow and showed a high agreement between the two, indicating that this method is useful for realistic I_c analysis.
