Truly Online Paging with Locality of Reference
The competitive analysis fails to model locality of reference in the online paging problem. To deal with it, Borodin et al. introduced the access graph model, which attempts to capture the locality of reference. However, the access graph model has a number of troubling aspects. The access graph has to be known in advance to the paging algorithm and the memory required to represent the access gr...
متن کاملOn Certain New Models for Paging with Locality of Reference
The competitive ratio is the most common metric in online algorithm analysis. Unfortunately, it produces pessimistic measures and often fails to distinguish between paging algorithms that have vastly differing performance in practice. An apparent reason for this is that the model does not take into account the locality of reference evidenced by actual input sequences. Therefore many alternative...
متن کاملOn List Update with Locality of Reference
We present a comprehensive study of the list update problem with locality of reference. More specifically, we present a combined theoretical and experimental study in which the theoretically proven and experimentally observed performance guarantees of algorithms match or nearly match. In the first part of the paper we introduce a new model of locality of reference that is based on the natural c...
متن کاملList Update with Locality of Reference
It is known that in practice, request sequences for the list update problem exhibit a certain degree of locality of reference. Motivated by this observation we apply the locality of reference model for the paging problem due to Albers et al. [STOC 2002/JCSS 2005] in conjunction with bijective analysis [SODA 2007] to list update. Using this framework, we prove that Move-to-Front (MTF) is the uni...
متن کاملTaming Large Classifiers with Rule Reference Locality
An important aspect of packet classification problem on which little light has been shed so far is the rule reference dynamics. In this paper, we argue that for any given classifier, there is likely a significant skew in the rule reference pattern. We term such phenomenon rule reference locality, which we believe stems from biased traffic pattern and/or the existence of “super-rules” that cover...
