A New Min-Cut Max-Flow Ratio for Multicommodity Flows,tio, capacity of a cut is scaled by the demand that has to cross the cut. In the denominator, the maximum concurrent flow value is used. Our new bound is proportional to log(.*) where .* is the cardinality of the minimal vertex cover of the demand graph.
