Evolvability of representations in complex system engineering: A survey

Andreas Richter, Mario Botsch, Stefan Menzel
2015 2015 IEEE Congress on Evolutionary Computation (CEC)  
A successful design optimization crucially depends on the underlying representation, which has to adapt to a variety of demands and changing boundary conditions.  ...  To quantify the potential of a representation, suitable quality criteria are needed. Evolvability is such a criterion, which has been derived from biological analysis.  ...  Mario Botsch is supported by the German National Research Foundation (DFG CoE 277: CITEC).  ...

On the Robustness of Controlled Deep Reinforcement Learning for Slice Placement [article]

Jose Jurandir Alves Esteves, Amina Boubendir, Fabrice Guillemin, Pierre Sens
2021 arXiv   pre-print
The evaluation results show that the proposed hybrid DRL-heuristic approach is more robust and reliable in case of unpredictable network load changes than pure DRL as it reduces the performance degradation  ...  Beyond that, we propose to evaluate the robustness of online learning for optimal network slice placement.  ...  ACKNOWLEDGMENT This work has been performed in the framework of 5GPPP MON-B5G project (www.monb5g.eu).  ...

Randomness and Determination, from Physics and Computing towards Biology [chapter]

Giuseppe Longo
2009 Lecture Notes in Computer Science  
In physics, differing probabilities, as a measure of randomness, evidentiate the differences between the various notions.  ...  As a recurring issue, the question will be raised of what randomenss means in biology, phylogenesis in particular.  ...  That is, contrary to the physical (classical) framework with its interval-based metric and topology, the measurement of the initial situation and at the boundary is exact in the case of a digital machine  ...
