Mutation and selection in a large population.
In this paper we study a large, but finite population, in which mutation and selection occur at a single genetic locus in a diploid organism. We provide theoretical results for the equilibrium allele frequencies, their variances and covariances and their equilibrium distribution, when the population size is larger than the reciprocal of the mean allelic mutation rate. We are also able to infer ...
متن کاملMutation-Selection Algorithm: A Large Deviation Approach
We consider a two-operator mutation-selection algorithm designed to optimize a tness function on the space of xed length binary strings. Mutation acts as in classical genetic algorithms, while the tness-based selection operates through a Gibbs measure (Boltzmann selection). The selective pressure is controlled by a temperature parameter. We provide a mathematical analysis of the convergence of ...
متن کاملA mutation and selection model in population genetics
We construct a new continuous time selection-mutation-recombination model for population dynamics, which describes the development of the distribution of the different gametes in the population. We show that cyclic mutation rates can result in stable and unstable limit cycles due to Hopf -bifurcation. In addition, we give a qualitative characterization of the whole dynamics in the simplex, whic...
متن کاملpassivity in waiting for godot and endgame: a psychoanalytic reading
this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
A New Selection Ratio for Large Population Sizes
Motivated by parallel optimization, we study the SelfAdaptation algorithm for large population sizes. We first show that the current version of this algorithm does not reach the theoretical bounds, then we propose a very simple modification, in the selection part of the evolution process. We show that this simple modification leads to big improvement of the speed-up when the population size is ...
