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.","lang":"eng"}],"publication":"Artificial Life","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"63"},{"_id":"238"}],"user_id":"15415","_id":"20177"},{"date_updated":"2022-01-06T06:54:21Z","volume":21,"date_created":"2020-10-22T09:56:20Z","author":[{"full_name":"Hamann, Heiko","last_name":"Hamann","first_name":"Heiko"},{"full_name":"Schmickl, Thomas","last_name":"Schmickl","first_name":"Thomas"},{"first_name":"Heinz","last_name":"Wörn","full_name":"Wörn, Heinz"},{"first_name":"Karl","full_name":"Crailsheim, Karl","last_name":"Crailsheim"}],"title":"Analysis of emergent symmetry breaking in collective decision making","doi":"10.1007/s00521-010-0368-6","publication_identifier":{"issn":["0941-0643","1433-3058"]},"publication_status":"published","issue":"2","year":"2012","intvolume":"        21","page":"207-218","citation":{"apa":"Hamann, H., Schmickl, T., Wörn, H., &#38; Crailsheim, K.

The linearity is achieved by optimizing the input matching and emitter degeneration. Safe operation conditions of heterojunction bipolar transistors at dc and high frequencies have been investigated at weak avalanche area.

The sensor consist of a 500 µm shorted half-wave coplanar waveguide transmission line in the top metal layer. Read-out of the sensor is performed by measurement of its reflection coefficient with an integrated multiprobe reflectometer and signal source. The MMIC has been fabricated in a 190-GHz f T SiGe:C BiCMOS technology and assembled on a printed circuit board. Functionality of the sensor is demonstrated with a stimulus frequency from 118 to 133GHz with immersion of the sensor into a binary methanol-ethanol mixture.","lang":"eng"}]},{"title":"A fully digital polar modulator for switch mode RF power amplifier","doi":"10.1109/ISCAS.2012.6271777","conference":{"end_date":"23.05.2012","start_date":"20.05.2012"},"date_updated":"2022-01-06T06:56:20Z","author":[{"first_name":"Philip","full_name":"Ostrovskyy, Philip","last_name":"Ostrovskyy"},{"full_name":"Scheytt, Christoph","id":"37144","last_name":"Scheytt","first_name":"Christoph"},{"full_name":"Lee, SungJun","last_name":"Lee","first_name":"SungJun"},{"first_name":"BongHyuk","full_name":"Park, BongHyuk","last_name":"Park"},{"first_name":"JaeHo","last_name":"Jung","full_name":"Jung, JaeHo"}],"date_created":"2021-09-14T13:01:24Z","year":"2012","page":"2385-2388","citation":{"ama":"Ostrovskyy P, Scheytt C, Lee S, Park B, Jung J.
