Vortrag: 7th IEEE International Conference on Services Computing (SCC 2010), Miami, Florida, USA; 05.07.2010 - 10.07.2010; in: "Proceedings of the 2010 IEEE Seventh International Conference on Services Computing (SCC 2010)", IEEE Computer Society, (2010), ISBN: 978-0-7695-4126-6; S. 97 - 104.

We present an optimization approach for service
compositions in large-scale service-oriented systems that are
subject to Quality of Service (QoS) constraints. In particular, we
leverage a composition model that allows a flexible specification
of QoS constraints by using constraint hierarchies. We propose
an extensible metaheuristic framework for optimizing such compositions.
It provides coherent implementation of common metaheuristic
functionalities, such as the objective function, improved
mutation or neighbor generation. We implement three metaheuristic
algorithms that leverage these improved operations. The
experiments show the efficiency of these implementations and the
improved convergence behavior compared to purely randomized
metaheuristic operators.
