Center node: "faster parametric shortest path and minimum balance algorithms"
  Abstract: We use Fibonacci heaps to improve a parametric shortest path algorithm of Karp and Orlin, and we combine our algorithm and the method of Schneider and Schneider's minimum-balance algorithm to obtain a faster minimum-balance algorithm.#R##N##R##N##R##N##R##N#For a graph with n vertices and m edges, our parametric shortest path algorithm and our minimum-balance algorithm both run in O(nm + n2 log n) time, improved from O(nm log n) for the parametric shortest path algorithm of Karp and Orlin and O(n2m) for the minimum-balance algorithm of Schneider and Schneider.#R##N##R##N##R##N##R##N#An important application of the parametric shortest path algorithm is in finding a minimum mean cycle. Experiments on random graphs suggest that the expected time for finding a minimum mean cycle with our algorithm is O(n log n + m).
