A theory representing the dynamics of in nite population Genetic Algorithms is given by using Eigen's evolution model. The effect of crossover is included to study the evolution of in nite population GAs. We present a theory of GA dynamics, in which we give discrete time equations for GA evolution including the mutation and crossover processes. The Walsh analysis of allele frequencies provides ...

BACKGROUND The human ultraviolet-B (UVB) experimental pain model induces cutaneous neurogenic inflammation, involves hyperalgesia, and is widely used as a pharmacological screening pain model. AIM To estimate the test-retest reliability of the UVB pain model by application of a comprehensive set of vasomotor and quantitative sensory assessment methods and to estimate sample sizes required for...

The investigation of genetic and evolutionary algorithms on Ising model problems gives much insight how these algorithms work as adaptation schemes. The Ising model on the ring has been considered as a typical example with a clear building block structure suited well for two-point crossover. It has been claimed that GAs based on recombination and appropriate diversity-preserving methods outperf...

The possibility of a new design concept for dual spin crossover based sensors for concomitant detection of both temperature and pressure is presented. It is conjectured from numerical results obtained by mean field approximation applied to a Ising-like model that using two different spin crossover compounds containing switching molecules with weak elastic interactions it is possible to simultan...

The genetic algorithm is a powerful heuristic for the solution of hard combinatorial problems and has been investigated by numer ous authors. Many problems, arising for example in communi. cation networks, possess stro ng two-dimensional characteristics. We describe a genetic algorit hm with a new crossover operator called block-uniform crossover, which exploits the two-dimensional character of...

Abstract Using Monte Carlo model of biological evolution we have discovered that populations can switch between two different strategies of their genomes’ evolution; Darwinian purifying selection and complementing the haplotypes. The first one is exploited in the large panmictic populations while the second one in the small highly inbred populations. The choice depends on the crossover frequenc...

We study numerically the crossover between organized and disorganized states of three non-equilibrium systems: the Poisson/coalesce random walk (PCRW), a one-dimensional spin system and a quasi one-dimensional lattice gas. In all cases, we describe this crossover in terms of the average spacing between particles/domain borders 〈S(t)〉 and the spacing distribution functions p(n)(s). The nature of...
