Spontaneous emergence of modularity in a model of evolving individuals.

چکیده
We investigate the selective forces that promote the emergence of modularity in nature. We demonstrate the spontaneous emergence of modularity in a population of individuals that evolve in a changing environment. We show that the level of modularity correlates with the rapidity and severity of environmental change. The modularity arises as a synergistic response to the noise in the environment in the presence of horizontal gene transfer. We suggest that the hierarchical structure observed in the natural world may be a broken-symmetry state, which generically results from evolution in a changing environment.

متن کاملPotentials of Evolving Linear Models in Tracking Control Design for Nonlinear Variable Structure Systems
Evolving models have found applications in many real world systems. In this paper, potentials of the Evolving Linear Models (ELMs) in tracking control design for nonlinear variable structure systems are introduced. At first, an ELM is introduced as a dynamic single input, single output (SISO) linear model whose parameters as well as dynamic orders of input and output signals can change through ...
متن کاملMining Overlapping Communities in Real-world Networks Based on Extended Modularity Gain
Detecting communities plays a vital role in studying group level patterns of a social network and it can be helpful in developing several recommendation systems such as movie recommendation, book recommendation, friend recommendation and so on. Most of the community detection algorithms can detect disjoint communities only, but in the real time scenario, a node can be a member of more than one ...
متن کاملA New Generation of Physicians in Sub-Saharan Africa?; Comment on “Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians”
This commentary follows up on an editorial by Eyal and colleagues in which these authors discuss the implications of the emergence of non-physician clinicians (NPCs) on the health labour market for the education of medical doctors. We generally agree with those authors and we want to stress the importance of clarifying the terminology to describe these practitioners and of defining more formall...
متن کاملEncouraging networks modularity by seeding motifs
We propose a motifs seeding method to encourage the emergence of modular structure during network evolution. Previous studies fail to trigger modularity on freeform evolving ANNs either when varying environmental factors or the evolutionary process itself. We extracted statistical profiles of 3-node and 4-node motifs from evolved networks, and then generated new networks by seeding the most use...
