In Optimal algorithm, it replaces the page that will not be used for the longest period of time. Optimal algorithm has the lowest page-fault rate of all algorithms. 相关知识点: 试题来源: 解析 最优算法替换未来最长时间不被访问的页面,具有最低的缺页率。 最优页面置换算法通过**预知未来的页面...
replacement strategyLRUOPT.LRU is the de facto standard page replacement strategy.It is well-known,however,that there are many situations where LRU behaves far from optimal.We present a replacement policy that approximates the optimal algorithm OPT more closely by predicting the time each page will...

In particular, the algorithm of Edmonds and Karp [50] has a complexity of at most O(n3logn). This monograph does not focus on computational aspects for optimal transport. This is a fascinating and very active area of contemporary research, and readers are directed to Peyré and Cuturi ...
We show that the discrete Sinkhorn algorithm—as applied in the setting of Optimal Transport on a compact manifold—converges to the solution of

5 In Appendix A, we provide an algorithm for solving this class of models with both forward-looking constraints and imperfect public monitoring.6 Our results on the consequences of imperfect credibility for optimal policy design differ from those of the “loose commitment” approach originally ...
If \beta > 2 then the optimal lower bound is \mathcal {O}(\sqrt{L}\alpha ^{-1/\beta }/\varepsilon ^{1/2-1/\beta }) [53, page 26]. In both cases, we achieve these optimal bounds with our algorithm (provided \beta _* = \beta ; see below) using, for example, Nesterov’...
Section 3.3 describes the algorithm used to solve the SBO. 3.1. Multi-criteria optimization model The decision variables of the multi-criteria optimization model are the prices for the rate components, denoted by the vector p. This study targets the rate design principles of economic efficiency, ...
