The authors deal with a generalization of the k-server problem, in which the servers are unequal. In the weighted server model each of the servers is assigned a positive weight. The cost associated with moving a server equals the product of the distance traversed and the server weight. A weighted k-server algorithm is called competitive if the competitive ratio depends only upon the number of servers. (i.e., the competitive ratio is independent of the weights associated with the servers and the…

Competitive Algorithms for Generalized k-Server in Uniform Metrics
The generalized k-server problem is considered in uniform metrics and the first f(k)-competitive algorithms for general k are given, including a deterministic and randomized algorithms with competitive ratio $O(k 2^k)$ and $O (k^3 \log k)$ respectively.
Weighted k-Server Bounds via Combinatorial Dichotomies
A doubly exponential lower bound on the competitive ratio of any deterministic online algorithm, that essentially matches the known upper bounds for the problem and closes a large and long-standing gap.

The Randomized Competitive Ratio of Weighted $k$-server is at least Exponential
This paper cuts down the triply exponential gap between the upper and lower bound to a singly exponential gap by proving that the competitive ratio is at least exponential in k, substantially improving on the previously known lower bound of about ln k.
On Randomized Memoryless Algorithms for the Weighted K-Server Problem
This work proves that there is an α<sub>k</sub> competitive memoryless algorithm for the weighted k-server problem on uniform spaces, and develops a framework to bound from above the competitive ratio of any randomized memoryless algorithms for this problem.
Online Paging with Heterogeneous Cache Slots
The deterministic upper bound is extended to the weighted variant of All-or-One Paging (a generalization of standard Weighted Paging), showing that it is also Θ(k).
Generalized Two-Server Problem
In the generalized two-server problem, two servers are given to serve requests r 2 X Y which arrive one by one and the objective is to minimize the total distance traveled by the two servers.
The Generalized Work Function Algorithm Is Competitive for the Generalized 2-Server Problem
It is shown that the generalized work function algorithm, $\mathrm{WFA}_{\lambda}$, is constant competitive for the generalized 2-server problem and given an outline for a possible extension to $k\geqslant2$ servers.

A new lower bound for deterministic one-server-algorithms in metric spaces with at least two points is shown, which implies the optimality of the algorithm on uniform metrics within a factor of 3 and forms the first distinctive difference to the k-server problem without delay.
