On the Generalization of the GMS Evolutionary Model
(2012) In Markov Processes and Related Fields 18(2). p.311-322- Abstract
- We study a generalization of the evolution model proposed by Guiol, Machado and Schinazi [4]. In our model, at each moment of time a random number of species is either born or removed from the system; the species to be removed are those with the lower fitnesses, fitnesses being some numbers in [0, 1]. We show that under appropriate conditions, a set of species approaches (in some sense) a sample from a uniform distribution on [f, 1], where f is an element of [0, 1), and that the total number of species forms a recurrent process in most other cases.
