An Improved Competitive Algorithm for Reordering Buffer Management


We design and analyze an online reordering buffer management algorithm with improved <i>O</i>(log <i>k</i>/log log <i>k</i>) competitive ratio for nonuniform costs, where <i>k</i> is the buffer size. This improves on the best previous result (even for uniform costs) of Englert and Westermann (2005) giving <i>O</i>(log <i>k</i>) competitive ratio, which was… (More)
