(2) The oracle returns the index of an arbitrary (i.e., worst-case) violated constraint. In this case, we give an algorithm with running time exponential in the number of variables.

Quantifying Competitiveness in Paging with Locality of Reference,r of page faults incurred by an optimal offline algorithm .. The bound is tight up to a small additive constant. Based on these expressions for .’s cost, we obtain nearly tight upper and lower bounds on .’s competitiveness, given any characteristic vector .. The resulting ratios range between 1 and

Approximation Algorithms for Computing Maximin Share Allocations,ents, for which it is already known that exact maximin share allocations do not always exist. We provide a .-approximation algorithm for this case, improving on the currently known ratio of .. Finally, we undertake a probabilistic analysis. We prove that in randomly generated instances, with high pr
