Let G = (v!E) be an undirected planar graph, and s, 1 E V, s # f. We present a linear algorithm to compute a set of edge-disjoint (s, t)-paths of maximum cardinality in G. In other words, the problem is to find a maximum unit flow from s to r in a non-weighted graph. The main purpose is not to show
