Some evolutionary stochastic processes

WebLecture 5 : Stochastic Processes I 1 Stochastic process A stochastic process is a collection of random variables indexed by time. An alternate view is that it is a probability distribution over a space of paths; this path often describes the evolution of some random value, or system, over time. In a deterministic process, there is a xed trajectory WebMar 21, 2012 · 1 INTRODUCTION. Natural evolution is an inherently stochastic process of population dynamics driven by mutations and selection, and the details of such evolutionary dynamics are increasingly becoming accessible via experimental investigation (Barrick et al., 2009; Chou et al., 2011; Finkel and Kolter, 1999; Pena et al., 2010; Ruiz-Jarabo et al., 2003).

WebThis paper proposes and analyzes a model of stochastic evolution in finite populations. Our model is a generalization of the Moran process of evolutionary biology (Moran [1962], Ewens [2004]) to frequency-dependent fitness. In this process, one individual per period “dies” and is replaced by a newcomer. The newcomer’s strategy is a WebAfterwards, the implantation of the BCS-SHF and some simplification to balance the computation efficiency and accuracy are discussed in sub-section 4.2.
