Abstract:
The concept of a fitness landscape arose in theoretical biology, while
that of effective fitness has its origin in evolutionary computation. Both
have emerged as useful conceptual tools with which to understand the dynamics
of evolutionary processes, especially in the presence of complex
genotype-phenotype relations. In this contribution we attempt to provide
a unified discussion of these two approaches, discussing both their
advantages and disadvantages in the context of some simple models. We
also discuss how fitness and effective fitness change under various
transformations of the configuration space of the underlying genetic
model, concentrating on coarse graining transformations and on a particular
coordinate transformation that provides an appropriate basis for
illuminating the structure and consequences of recombination.
