Integer equal flows

The integer equal flow problem is an NP-hard network flow problem, in which all arcs in given sets R1,…,R[subscript ℓ] must carry equal flow. We show that this problem is effectively inapproximable, even if the cardinality of each set R[subscript k] is two. When ℓ is fixed, it is solvable in polynom...
