Rense CortenDepartment of Sociology, Utrecht University, The Netherlands benefit from the novel approaches presented in this book.

“Corten’s book provides a very nice example of a theorizing-modelling-empirical testing cycle which can advance sociological investigation. This is a worth-reading book for every scholar who wants to understand the research life cycle in computational sociology. It is methodologically rigorous as well as inspirational and enlightening.”  (Journal of Artificial Societies and Social Simulation, 1 May 2014)
