| Given an undirected edge-weighted network in which one edge capacity is allowed to vary, we propose in this paper a polynomial algorithm that needs only two 2-cuttrees computations to provide the all pairs maximum 2-route flow values. Moreover, we provide an extension to the case where k edge capacities may vary, and show that 2^k 2-cut-trees computations are necessary in order to determine the all pairs maximum 2-route-flow values. This makes our algorithm polynomial whenever k = O(polylog n). |
