Strongly Competitive Algorithms for Caching with Pipelined Prefetching this model we consider the following problem. Suppose that a program makes a sequence of . accesses to data blocks. The cache can hold . blocks, where . < .. An access to a block in the cache incurs one time unit, and fetching a missing block incurs . time units. A fetch of a new block can be initi

A General Decomposition Theorem for the ,-Server Problem. + 1 points, the theorem given here allows an arbitrary number of points in the underlying metric space. This theorem implies .(polylog(.))-competitive randomized algorithms for certain metric spaces consisting of a polylogarithmic number of widely separated sub-spaces, and takes a first step towar

On the Approximability of the Minimum Test Collection Problemtion . of . such that for every pair of elements (.) in . there exists a test in . that contains exactly one of . and .. It is well known that the greedy algorithm gives a 1 + 2lnn approximation for the test collection problem where ., the size of the ground set. In this paper, we show that this alg
