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

This paper describes a prototype parallel algorithm for approximating eigenvalues of a dense nonsymmetric matrix on a linear, synchronous processor array. The algorithm is a parallel implementation of the explicitly-shifted QR, employing n distributed-memory processors to deliver all eigenvalues in
An n-element knapsack problem has 2" possible solutions to search over, so a task which can be accomplished in 2" trials if an exhaustive search is used. Due to the exponential time in solving the knapsack problem, the problem is considered to be very hard. In the past decade, much effort has been d
