Better Bounds for Incremental Medians
In the incremental version of the well-known k-median problem the objective is to compute an incremental sequence of facility sets F1 ⊆ F2 ⊆ .... ⊆ Fn, where each Fk contains at most k facilities. We say that this incremental medians sequence is R-competitive if the cost of each Fk is at most R times the optimum cost of k facilities. The smallest such R is called the competitive ratio of the se...
متن کاملBetter Bounds for Incremental Frequency Allocation in Bipartite Graphs
We study frequency allocation in wireless networks. A wireless network is modeled by an undirected graph, with vertices corresponding to cells. In each vertex we have a certain number of requests, and each of those requests must be assigned a different frequency. Edges represent conflicts between cells, meaning that frequencies in adjacent vertices must be different as well. The objective is to...
متن کاملGeneral Bounds for Incremental Maximization
We propose a theoretical framework to capture incremental solutions to cardinality constrained maximization problems. The defining characteristic of our framework is that the cardinality/support of the solution is bounded by a value k ∈ N that grows over time, and we allow the solution to be extended one element at a time. We investigate the best-possible competitive ratio of such an incrementa...
متن کاملBetter Bounds for Perpetual Gossiping
In the perpetual gossiping problem, introduced by Liestman and Richards, information may be generated at any time and at any vertex of a graph G; adjacent vertices can communicate by telephone calls. We define Wk(G) to be the minimum w such that, placing at most k calls each time unit, we can ensure that every piece of information is known to every vertex within w time units of its generation. ...
متن کاملBetter Bounds for Graph Bisection
We introduce new lower bounds for the minimum graph bisection problem. Within a branch-and-bound framework, they enable the solution of a wide variety of instances with tens of thousands of vertices to optimality. Our algorithm compares favorably with the best previous approaches, solving long-standing open instances in minutes.
