Abstract
NK fitness landscapes are stochastically generated fitness functions on bit
strings, parameterized (with N genes and K interactions between genes) so as to
make them tunably `rugged'. Under the `natural' genetic operators of bit­flipping
mutation or recombination, NK landscapes produce multiple domains of attrac­
tion for the evolutionary dynamics. NK landscapes have been used in models of
epistatic gene interactions, coevolution, genome growth, and Wright's shifting bal­
ance model of adaptation. Theory for adaptive walks on NK landscapes has been
derived, and generalizations that extend beyond Kauffman's original framework
have been utilized in these applications.
