摘要
We show that the greedy highest density first (HDF) algorithm is (1 + epsilon)-speed O(1) -competitive for the problem of minimizing the lp norms of weighted flow time on in identical machines. Similar results for minimizing unweighted flow provide insight into the power of migration. (c) 2005 Elsevier B.V. All rights reserved.
