The paging problem is deΓΏned as follows: we are given a two-level memory system, in which one level is a fast memory, called cache, capable of holding k items, and the second level is an unbounded but slow memory. At each given time step, a request to an item is issued. Given a request to an item p,

This paper studies two methods for improving the competitive efficiency of on-line paging algorithms: in the first, the on-line algorithm can use more pages; in the second, it is allowed to have a lookahead, or in other words, some partial knowledge of the future. The paper considers a new measure f
In this paper we give deterministic competitive k-server algorithms for all k and all metric spaces. This settles the k-server conjecture up to the competitive ratio, The best previous result for general metric spaces was a three-server randomized competitive algorithm and a nonconstructive proof th
We compare a number of training algorithms for competitive learning networks applied to the problem of vector quantization for data compression. A new competitive-learning algorithm based on the "conscience" learning method is introduced. The performance of competitive learning neural networks and t
