Using a well-known cooperative coevolutionary function optimization framework, a very simple cooperative coevolutionary (1+1) EA is defined. This algorithm is investigated in the context of expected optimization time. The focus is on the impact the cooperative coevolutionary approach has and on the possible advantage it may have over more traditional evolutionary approaches. Therefore, a system...

In this issue, Bergmüller et al. (2007) have provided a valuable review paper, re-establishing cooperative breeding within a theoretical framework in field studies of cooperative breeding vertebrates. I am in agreement with the authors in their outlook and suggestions. In this critical review, I wish to (1) review the costs and benefits approach previously taken in the field, (2) evaluate commu...

To reuse one or several existing systems in order to develop a complex system is a common practice in software engineering. This approach can be justified by the fact that it is often difficult for a single Information System (IS) to accomplish all the requested tasks. So, one solution is to combine many different ISs and make them collaborate in order to realize these tasks. We previously prop...

This article proposes a systematic approach to statistical testing for cooperative systems consisting of autonomous mobile agents. Based on Coloured Petri Net models of cooperative behaviour, it analyses different sources of randomness and defines an automatic test case generation procedure to derive cooperative scenarios according to a given operational profile. As an example, the approach is ...

This paper presents an approach to Search Based Software Project Management based on Cooperative Co-evolution. Our approach aims to optimize both developers’ team staffing and work package scheduling through cooperative co-evolution to achieve early overall completion time. To evaluate our approach, we conducted an empirical study, using data from four real-world software projects. Results indi...
