We present a new algorithm for the Hitchcock transportation problem. On instances with n sources and k sinks, our algorithm has a worst-case running time of O(nk 2 (log n + k log k)). It closes a gap between algorithms with running time linear in n but exponential in k and a polynomialtime algorithm

In this paper an inverse problem of the weighted shortest arborescence problem is discussed. That is. given a directed graph G and a set of nonnegative costs on its arcs. we need to modify those costs as little as possible to ensure that T, a given (.I-arborescence of G, is the shortest one. It is

## Several balanced optimization problems have been analysed in the literature. Here, the balanced network flow problem in the uniform case is studied, and it is shown that it can be solved by the Newton's approach in O(n' log3 n) max-flow computations. The key of the proof is an extension of Rad
