A Theoretical Comparison of LRU and LRU-K
Weba online paging/caching algorithm is to evict pages from the cache in a good way that minimizes the number of cache misses. This algorithm is an online algorithm because generally we do not know what the requests will be from the beginning. First we introduce the concepts of Least Recently Used (LRU) and Round.

WebSep 28, 2010 · The paging algorithm Least Recently Used Second Last Request (LRU-2) was proposed for use in database disk buffering and shown experimentally to perform better than Least Recently Used (LRU). We compare LRU-2 and LRU theoretically, using both the standard competitive analysis and the newer relative worst order analysis. The … WebFor deterministic algorithms, we show that an adaptation of LRU is strongly competitive, while for the randomized case we show that by adapting the classical Mark algorithm we get an algorithm with a competitive ratio larger than the lower bound by a multiplicative factor of approximately 1.7.
