Greedy adaptive walks on a correlated fitness landscape
Su-Chan Park, Johannes Neidhart, Joachim Krug
We study adaptation of a haploid asexual population on a fitness landscape defined over binary genotype sequences of length . We consider greedy adaptive walks in which the popu…
Phase transition in random adaptive walks on correlated fitness landscapes
Su-Chan Park, Ivan G. Szendro, Johannes Neidhart +1
We study biological evolution on a random fitness landscape where correlations are introduced through a linear fitness gradient of strength . When selection is strong and mutati…
Multidimensional epistasis and the transitory advantage of sex
Stefan Nowak, Johannes Neidhart, Ivan G. Szendro +1
Identifying and quantifying the benefits of sex and recombination is a long standing problem in evolutionary theory. In particular, contradictory claims have been made about the ex…
Adaptation in tunably rugged fitness landscapes: The Rough Mount Fuji Model
Johannes Neidhart, Ivan G. Szendro, Joachim Krug
Much of the current theory of adaptation is based on Gillespie's mutational landscape model (MLM), which assumes that the fitness values of genotypes linked by single mutational st…
Exact Results for Amplitude Spectra of Fitness Landscapes
Johannes Neidhart, Ivan G. Szendro, Joachim Krug
Starting from fitness correlation functions, we calculate exact expressions for the amplitude spectra of fitness landscapes as defined by P.F. Stadler [J. Math. Chem. 20, 1 (1996)]…
Adaptive walks and extreme value theory
Johannes Neidhart, Joachim Krug
We study biological evolution in a high-dimensional genotype space in the regime of rare mutations and strong selection. The population performs an uphill walk which terminates at…
