Genetically controlled random search: a global optimization method for continuous multidimensional functions
A new stochastic method for locating the global minimum of a multidimensional function inside a rectangular hyperbox is presented. A sampling technique is employed that makes use ...

Random Landmarking in Mobile, Topology-Aware Peer-to-Peer Networks
DHTs can locate objects in a peer-to-peer network within an efficient amount of overlay hops. Since an overlay hop is likely to consist of multiple physical hops, the ratio betwee...

Efficient Parallel Query Processing by Graph Ranking
In this paper we deal with the problem of finding an optimal query execution plan in database systems. We improve the analysis of a polynomial-time approximation algorithm due to M...

Network Design via Core Detouring for Problems without a Core
Some of the currently best-known approximation algorithms for network design are based on random sampling. One of the key steps of such algorithms is connecting a set of source nod...
