Fractional Packing of T-joins

Given a graph with nonnegative capacities on its edges, it is well known that the weight of a minimum T-cut is equal to the value of a maximum packing of T-joins. Padberg-Rao's algorithm finds a minimum weight T-cut but it does not produce a T-join packing, we present a polynomial combinatorial algorithm for finding an optimal T-join packing.
