D-separation algorithm

WebWe propose a new exact separation algorithm for the capacitated case which has the same running time as for the uncapacitated case. For the sake of brevity, however, we will restrict our introduction to the case of perfect 1-capacitated b -matchings, which includes, for example, the separation problem for perfect 2-matchings.
