Evolution of robust and efficient system topologies

Cellular Immunology, 2006
Mutation/selection algorithms were applied to increase the efficiency and the robustness of sparse random networks. Selection for better efficiency leads to the well-known star topology, while selection for robustness only results in a relatively dense core and a small periphery.

Robustness and network evolution—an entropic principle

Physica A: Statistical Mechanics and its Applications, 2005
Abstract This article introduces the concept of network entropy as a characteristic measure of network topology. We provide computational and analytical support for the hypothesis that network entropy is a quantitative measure of robustness. We formulate an evolutionary model based on entropy as a selective criterion and show that (a) it predicts the

Neuro-Evolution and Robustness: A Case Study

2018 IEEE Games, Entertainment, Media Conference (GEM), 2018
We designed and implemented a game with a nonplaying character controlled by a neural network, where the weight set determines the character's next move. The weight sets were improved using neuro-evolution, where a genetic algorithm alters the weights of the neural network.

Evolution of Phenotypic Robustness

2005
Abstract Evolutionary biology, in the neo-Darwinian tradition, is based on the study of genetic and phenotypic variation and its fate in populations. Thus, the observation that the genetic variability of a trait is itself influenced by the genotype has obvious theoretical implications [49, 55].

Robustness revisited: On the neutral evolution of centrality and localization

Proceedings of the National Academy of Sciences of the United States of America
This study investigates the intricate interplay among neutral landscape structure, mutation rate, recombination rate, and population dynamics in shaping evolutionary robustness. We provide a comprehensive framework that elucidates how different evolutionary forces interact to influence genotypic robustness and localization within haploid and diploid ...

Plasticity, Robustness, Development and Evolution

2011
How do we understand and explain the apparent dichotomy between plasticity and robustness in the context of development? Can we identify these complex processes without resorting to 'either/or' solutions? Written by two leaders in the field, this is the first book to fully unravel the complexity of the subject, explaining that the epigenetic processes ...
