    Simulations on evolutionary phenomena with ageing models
    (2006) Schwämmle, Veit; Herrmann, Hans (Prof.)
    The idea of reducing the characteristics of highly complex systems to some basic features without losing the essential informations has been successful for the comprehension of not only physical systems. The experience in treating systems which consist of many elements that interact over different time scales as well as over wide distances, has opened many interdisciplinary fields to statistical physicists. Although animals and human beings behave in a much more complex way than for instance atoms or molecules, simple statistical models are able to reproduce many biological phenomena. The goal is to reproduce the collective behaviour of a large number of organisms: their individual properties are not of crucial importance. Due to the strongly increasing computer power along the last fifty years, computational models have gained more and more importance for research in many areas. The limitation of analytical models to describe accurately non-linear systems with critical behavior makes computational models nearly irreplaceable.
