Let C be the clutter of odd circuits of a signed graph Γ°G; SΓ: For nonnegative integral edge-weights w; we are interested in the linear program minΓ°w t x: xΓ°CΓ51; for C 2 C; and x50Γ; which we denote by (P). The problem of solving the related integer program clearly contains the maximum cut problem,
## Abstract In an earlier paper 3, we studied cycles in graphs that intersect all edgeβcuts of prescribed sizes. Passing to a more general setting, we examine the existence of __T__βjoins in grafts that intersect all edgeβcuts whose size is in a given set __A__ β{1,2,3}. In particular, we character
We present an algorithm, APD, that solves the distance version of the all-pairs-shortest-path problem for undirected, unweighted \(n\)-vertex graphs in time \(O(M(n) \log n)\), where \(M(n)\) denotes the time necessary to multiply two \(n \times n\) matrices of small integers (which is currently kno
We consider the following problem. Let G s V, E be an undirected planar graph and let s, t g V, s / t. The problem is to find a set of pairwise edge-disjoint paths in G, each connecting s with t, of maximum cardinality. In other words, the problem is to find a maximum unit flow from s to t. The fast
