Optimal caching problem
WebDec 17, 2024 · In this paper, we study data caching problem in edge computing in order to minimize the system cost, including data caching cost, data transmission cost and data purchase cost. The traditional data center is only the choice to purchase data, the data is always available after purchasing. WebManaging the cache in a good way is, therefore, necessary in order for programs to run fast. The goal of a caching algorithm is to evict pages from the cache in a way that minimizes …

WebAchieving the delay optimality of the caching problem needs to solve the Bellman equation of the SMDP, but it leads to the curse of dimensionality. We decompose the global … WebFeb 16, 2024 · Interestingly, our findings reveal that the optimal caching policy necessitates unequal load-splitting over the edge-caches even when all conditions are symmetric. Moreover, we find that edge-caches with higher load will generally cache fewer but relatively more popular content.
WebFeb 18, 2024 · 4.1 Problem development using optimization method We adopt the total missing probability as our system performance metric, which denotes the average probability that a typical user cannot find the requested file in the cache of each BS within their effective radius. For the ease of analysis, we assume a typical user located at origin o.

WebJan 18, 2024 · Online Caching with Optimal Switching Regret Samrat Mukhopadhyay, Abhishek Sinha We consider the classical uncoded caching problem from an online learning point-of-view. A cache of limited storage capacity can hold files at a time from a large catalog. A user requests an arbitrary file from the catalog at each time slot. WebDec 17, 2024 · Optimal Caching is a technique that reduces the number of cache misses compared to any other method of cache management. There is a good course on …
WebThe problem arises when something is requested that's not in the cache. So let's say the next request is for the data item e. Now remember, you have to bring e into the cache and of course you have to evict one of these four pieces of data to make room for it, and your …
WebA problem can be optimized using dynamic programming if it: has an optimal substructure. has overlapping subproblems. If a problem meets those two criteria, then we know for a fact that it can be optimized using dynamic programming. Optimal Substructure chinese in windsor caWebJun 7, 2024 · In fact, we show that optimal caching with SCH is NP-hard even for a single cache. To this end, we formulate the optimal femto-caching problem with SCH in a sufficiently generic setup and propose efficient algorithms with provable performance. grand optical gardanneWebDec 17, 2024 · Optimal Caching is a technique that reduces the number of cache misses compared to any other method of cache management.
