An Improved Diversity Mechanism for Solving Constrained Optimization Problems Using a Multimembered Evolution Strategy
This paper presents an improved version of a simple evolution strategy (SES) to solve global nonlinear optimization problems. As its previous version, the approach does not require...

Optimizing diversity
We consider the problem of minimizing the size of a set system G such that every subset of {1, . . . , n} can be written as a disjoint union of at most k members of G, where k and...

Multi-hop Cooperative Wireless Networks: Diversity Multiplexing Tradeoff and Optimal Code Design
In this paper, we consider single-source, single-sink (ss-ss) multi-hop relay networks, with slow-fading Rayleigh links and single-antenna relay nodes operating under the half-dupl...

Cost Models DO Matter: Providing Cost Information for Diverse Data Sources in a Federated System
An important issue for federated systems of diverse data sources is optimizing cross-source queries, without building knowledge of individual sources into the optimizer. This pape...
