Optimal Mutation Rates on Static Fitness Landscpes
M. Nilsson
We study the evolution of mutation rates for an asexual population living on a static fitness landscape, consisting of multiple peaks forming an evolutionary staircase. The optimal…

Optimal Mutation Rates in Dynamic Environments
Martin Nilsson, Nigel Snoad
In this paper we study the evolution of the mutation rate for simple organisms in dynamic environments. A model with multiple fitness coding loci tracking a moving fitness peak is…

Quasispecies evolution on a fitness landscape with a fluctuating peak
Martin Nilsson, Nigel Snoad
A quasispecies evolving on a fitness landscape with a single peak of fluctuating height is studied. In the approximation that back mutations can be ignored, the rate equations can…
