Metastable Evolutionary Dynamics: Crossing Fitness Barriers or Escaping via Neutral Paths?
Erik van Nimwegen, James P. Crutchfield
We analytically study the dynamics of evolving populations that exhibit metastability on the level of phenotype or fitness. In constant selective environments, such metastable beha…
The Evolutionary Unfolding of Complexity
James P. Crutchfield, Erik van Nimwegen
We analyze the population dynamics of a broad class of fitness functions that exhibit epochal evolution---a dynamical behavior, commonly observed in both natural and artificial evo…
Optimizing Epochal Evolutionary Search: Population-Size Dependent Theory
Erik van Nimwegen, James P. Crutchfield
Epochal dynamics, in which long periods of stasis in an evolving population are punctuated by a sudden burst of change, is a common behavior in both natural and artificial evolutio…
Optimizing Epochal Evolutionary Search: Population-Size Independent Theory
Erik van Nimwegen, James P. Crutchfield
Epochal dynamics, in which long periods of stasis in population fitness are punctuated by sudden innovations, is a common behavior in both natural and artificial evolutionary proce…
