This paper describes a parallel algorithm for selecting activation functionsof an articial network. For checking the eciency of this algorithm a count ofmultiplicative and additive operations is used.[...]

Cloud Computing is a topic that has gained momentum in the last years. Current studies show that anincreasing number of companies is evaluating the promised advantages and considering making use ofcloud services. In this paper we investigate the phenomenon of cloud computing and its importance...

This short comment on Epstein's (2008) paper and on the response by Thompson and Derr argues that the symmetry between explanation and prediction cannot satisfactorily be discussed without making clear what prediction means - depending on which connotations the authors have with 'prediction'...

This special section includes papers originally presented at a workshop on \'Epistemological Perspectives on Simulation\' in July 2004 at the University of Koblenz, in which some thirty colleagues participated. It had been our impression that there was (and still is) a small, but growing number...

In our paper, we replicate simulation experiments carried out some 30 years ago by Jay M. Anderson who then tried to find out which measures should be taken to avoid the eutrophication of a lake. In his DYNAMO model, he simulated the development of a lake under cultural eutrophication, i.e....
