Drift reversal in asymmetric coevolutionary conflicts: influence of microscopic processes and population size

Drift reversal in asymmetric coevolutionary conflicts: Influence of microscopic processes and population size

The coevolutionary dynamics in finite populations currently is investigated in a wide range of disciplines, as chemical catalysis, biological evolution, social and economic systems. The dynamics of those systems can be formulated within the unifying framework of evolutionary game theory. However it is not a priori clear which mathematical description is appropriate when populations are not infi...

the influence of corpus luteum on follicular fluid composition from different size follicles and their relationship to serum concentrations in sanjabi ewes

the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...

language learning strategies and vocabulary size of iranian efl learners

learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...

Coevolutionary Optimization Algorithm with Dynamic Sub-population Size

This paper proposes a coevolutionary optimization algorithm called DCOA. DCOA mainly focuses on how to adjust sub-population size self-adaptively so as to improve the optimizing performance. To achieve this, a strategy is introduced which consists of three rules: internal competition, external competition and spontaneous growth rules. These rules can control individual reproduction and eliminat...
