Monotonicity of fitness landscapes and mutation rate control
A common view in evolutionary biology is that mutation rates are minimised. However, studies in combinatorial optimisation and search have shown a clear advantage of using variable mutation rates as a control parameter to optimise the performance of evolutionary algorithms. Much biological theory in this area is based on Ronald Fisher's work, who used Euclidean geometry to study the relation be...
متن کامل2-bit Flip Mutation Elementary Fitness Landscapes
Genetic Programming parity with only XOR is not elementary. GP parity can be represented as the sum of k/2 + 1 elementary landscapes. Statistics, including fitness distance correlation (FDC), of Parity’s fitness landscape are calculated. Using Walsh analysis the eigen values and eigenvectors of the Laplacian of the two bit flip fitness landscape are given. Tests support λ/d as a measure of the ...
متن کاملFitness landscapes: an alternative theory for the dominance of mutation.
Deleterious mutations tend to be recessive. Several theories, notably those of Fisher (based on selection) and Wright (based on metabolism), have been put forward to explain this pattern. Despite a long-lasting debate, the matter remains unresolved. This debate has focused on the average dominance of mutations. However, we also know very little about the distribution of dominance coefficients a...
متن کاملDynamic fitness landscapes: Expansions for small mutation rates
We study the evolution of asexual microorganisms with small mutation rate in fluctuating environments, and develop techniques that allow us to expand the formal solution of the evolution equations to first order in the mutation rate. Our method can be applied to both discrete time and continuous time systems. While the behavior of continuous time systems is dominated by the average fitness land...
