The k server with preferences problem

WebAbstract. We prove that the work function algorithm for the k-server problem has a competitive ratio at most 2k – 1. Manasse et al. [1988] conjectured that the competitive ratio for the k-server problem is exactly k (it is trivially at least k); previously the best-known upper bound was exponential in k. WebThe famous k-Server Problem covers plenty of resource allocation scenarios, and several variations have been studied extensively for decades. ... Therefore, we present a new …

The K-Server Problem via a Modern Optimization Lens

WebAbstract. The reinforcement learning paradigm has been shown to be an effective approach in solving the k-server problem.However, this approach is based on the Q-learning algorithm, being subjected to the curse of dimensionality problem, since the action-value function (Q-function) grows exponentially with the increase in the number of states and actions. The k-server problem is a problem of theoretical computer science in the category of online algorithms, one of two abstract problems on metric spaces that are central to the theory of competitive analysis (the other being metrical task systems). In this problem, an online algorithm must control the movement of a set of k servers, represented as points in a metric space, and handle requests that are also in the form of points in the space. As each request arrives, the algo… full truckload freight cost per mile https://rhinotelevisionmedia.com

WebSpecifically, we show that the infinite server problem has bounded competitive ratio if and only if the (h,k) -server problem has bounded competitive ratio for some k = O ( h ). We give a lower bound of 3.146 for the competitive ratio of the infinite server problem, which holds even for the line and some simple weighted stars.
