Abstract

Suppose G is a finite graph and let T ⊆ V ( G ) be a subset of its vertices throughout referred to as terminals . The problem MAXIMUM DISJOINT T -PATHS (MDT-P) is to find a family of maximum pairwise disjoint paths connecting pairs of terminals. MDT-P is a nontrivial extension of the maximum matching problem; the latter being equivalent to the special case T = V . We present a dual problem of minimum odd T-disconnector , an appropriate minimax theorem and an O( n 4 ) algorithm constructing optimal solutions for both primal and dual problems.
