## Abstract Given an undirected multigraph __G__ = (__V__, __E__) and a requirement function __r__~λ~: () → __Z__^+^ (where () is the set of all pairs of vertices and __Z__^+^ is the set of nonnegative integers), we consider the problem of augmenting __G__ by the smallest number of new edges so tha

✦ Synopsis
We prove theorems on edge splittings and edge-connectivity augmentation in directed hypergraphs, extending earlier results of Mader and Frank, respectively, on directed graphs.

We give improved randomized Monte Carlo algorithms for undirected edge splitting and edge connectivity augmentation problems. Our algorithms run in time ˜2 Ž . Ž . O n on n-vertex graphs, making them an ⍀ mrn factor faster than the best known deterministic ones on m-edge graphs.
Let A(n, k, t) denote the smallest integer e for which every kconnected graph on n vertices can be made (k + t)-connected by adding e new edges. We determine A(n, k, t) for all values of n, k, and t in the case of (directed and undirected) edge-connectivity and also for directed vertex-connectivity
