A 3.3904-Competitive Online Algorithm for List Update with Uniform Costs

Mateusz Basiak, Marcin Bienkowski, Martin Böhm +4

We consider the List Update problem where the cost of each swap is assumed to be 1. This is in contrast to the ``standard'' model, in which an algorithm is allowed to swap the requ…

Structural Properties of Search Trees with 2-way Comparisons

Sunny Atalig, Marek Chrobak, Erfan Mousavian +2

Optimal 3-way comparison search trees (3WCST's) can be computed using standard dynamic programming in time O(n^3), and this can be further improved to O(n^2) by taking advantage of…

Classification via Two-Way Comparisons

Marek Chrobak, Neal E. Young

Given a weighted, ordered query set and a partition of into classes, we study the problem of computing a minimum-cost decision tree that, given any query in , uses e…

Online Paging with Heterogeneous Cache Slots

Marek Chrobak, Samuel Haney, Mehraneh Liaee +4

It is natural to generalize the online -Server problem by allowing each request to specify not only a point , but also a subset of servers that may serve it. For uniform…
