Influence of genetic interactions schemes on adaptive walks — •Stefan Nowak and Joachim Krug — Institut für Theoretische Physik, Universität zu Köln

The NK landscape is a model for a genotype to fitness mapping where epistatic interactions between loci can be explicitly defined. We study adaptive walks on this landscape to analyse the effects of different interaction schemes. For simple versions of the model, the length of the walk and the attained fitness can be computed exactly. For general NK landscapes, we show by Monte Carlo simulations that these quantities are strongly correlated to the so-called rank of the interaction scheme.
