Protein structures sustain evolutionary drift

Exploration of Evolutionary Relations between Protein Structures

We describe a new method for the exploration of evolutionary relations between protein structures. The approach is based on the ESSM algorithm for detecting structural mutations, the output of which is then used for construction of fold space graphs. Fold space graphs can be regarded as a convenient tool for visualization and analysis of evolutionary relationships between protein structures, pr...

Evolutionary Drift and Equilibrium Selection

This paper develops an approach to equilibrium selection in game theory based on studying . the learning process through which equilibrium is achieved. The differential equations derived from models of interactive learning typically have stationary states that are not isolated. Instead, Nash equilibria that specify different out-of-equilibrium behaviour appear in connected components of station...

Evolutionary Drift and Equilibrium Selection1

This paper develops an approach to equilibrium selection in game theory based on studying the equilibriating process through which equilibrium is achieved. The di®erential equations derived from models of interactive learning typically have stationary states that are not isolated. Instead, Nash equilibria that specify the same behavior on the equilibrium path, but di®erent out-of-equilibrium be...

Evolutionary Drift Among Isophenotypic Genotypes

Isogeometric Topology Optimization of Continuum Structures using an Evolutionary Algorithm

Topology optimization has been an interesting area of research in recent years.  The main focus of this paper is to use an evolutionary swarm intelligence algorithm to perform Isogeometric Topology optimization of continuum structures.  A two-dimensional plate is analyzed statically and the nodal displacements are calculated.  The nodal displacements using Isogeometric analysis are found to be ...
