We investigate the relation between macro-scale properties (such as modularity and regularity) and micro-scale properties in Neural Network controllers. We show how neurons capable of multiplicative-like arithmetic operations may increase the performance of controllers in several ways whenever challenging control problems with non-linear dynamics are involved. This paper provides evidence that performance and robustness of evolved controllers can be improved by a combination of carefully chosen micro- and macro-scale neural network properties.}}, author = {{Hamann, Heiko and Stradner, Jürgen and Bredeche, Nicolas and Cazenille, Leo}}, booktitle = {{14th Annual Genetic and Evolutionary Computation Conference, GECCO 2012}}, pages = {{89--96}}, publisher = {{ACM}}, title = {{{Impact of Neuron Models and Network Structure on Evolving Modular Robot Neural Network Controllers}}}, doi = {{10.1145/2330163.2330177}}, year = {{2012}}, } @inproceedings{20174, abstract = {{As a contribution to the efforts towards robotic systems of higher flexibility we present our concept of morphologically dynamic robots.

The difficulty is increased even more in the case of settings with multiple interacting agents. We apply the artificial homeostatic hormone system (AHHS) approach, which is inspired by the signaling network of unicellular organisms, to control a system of several independently acting agents decentrally. The approach is designed for evaluation-minimal, artificial evolution in order to be applicable to complex modular robotics scenarios. The performance of AHHS controllers is compared with neuroevolution of augmenting topologies (NEAT) in the coupled inverted pendulums benchmark. AHHS controllers are found to be better for multimodular settings. We analyze the evolved controllers with regard to the usage of sensory inputs and the emerging oscillations, and we give a nonlinear dynamics interpretation. The generalization of evolved controllers to initial conditions far from the original conditions is investigated and found to be good. Similarly, the performance of controllers scales well even with module numbers different from the original domain the controller was evolved for. Two reference implementations of a similar controller approach are reported and shown to have shortcomings. We discuss the related work and conclude by summarizing the main contributions of our work.}}, author = {{Hamann, Heiko and Schmickl, Thomas and Crailsheim, Karl}}, issn = {{1064-5462}}, journal = {{Artificial Life}}, number = {{2}}, pages = {{165--198}}, title = {{{A Hormone-Based Controller for Evaluation-Minimal Evolution in Decentrally Controlled Systems}}}, doi = {{10.1162/artl_a_00058}}, volume = {{18}}, year = {{2012}}, } @article{20178, author = {{Hamann, Heiko and Schmickl, Thomas and Wörn, Heinz and Crailsheim, Karl}}, issn = {{0941-0643}}, journal = {{Neural Computing and Applications}}, number = {{2}}, pages = {{207--218}}, title = {{{Analysis of emergent symmetry breaking in collective decision making}}}, doi = {{10.1007/s00521-010-0368-6}}, volume = {{21}}, year = {{2012}}, } @inproceedings{20179, author = {{Hamann, Heiko and Engelbrecht, Andreas and Birattari, Mauro and Dorigo, Marco and Blum, Christian and Stuetzle, Thomas and Christensen, Anders Lyhne and Gross, Roderich}}, booktitle = {{Swarm Intelligence: 8th International Conference, ANTS 2012}}, isbn = {{9783642326493}}, issn = {{0302-9743}}, pages = {{168--179}}, publisher = {{Springer}}, title = {{{Towards Swarm Calculus: Universal Properties of Swarm Performance and Collective Decisions}}}, doi = {{10.1007/978-3-642-32650-9_15}}, volume = {{7461}}, year = {{2012}}, } @inbook{2021, author = {{Krimphove, Dieter}}, booktitle = {{Finanzierung und Investition}}, editor = {{Schmeisser, Wilhelm and Krimphove, Dieter and Zündorf, Horst and Toebe, Marc and Hannemann, Gerfried}}, pages = {{140 – 179}}, publisher = {{UTB}}, title = {{{Kreditfinanzierung durch Kreditsicherheiten; Kapitel 6}}}, year = {{2012}}, }
