In this paper, we examine the usefulness of recombination from two points of view. First, the
problem of crossover disruption is investigated. This is done by comparing two Genetic …

We present numerical results on Kauffman's NK landscape family indicating that the optimal
distance at which to search for fitter variants depends on both the current fitness and the …

Usually the offspring-parent fitness correlations is used to visualize and analyze some
characteristics of fitness landscapes such as evolvability. In this paper, we introduce a more …

In evolution theory the concept of a fitness landscape has played an important role,
evolution itself being portrayed as a hill-climbing process on a rugged landscape. It is shown …

Evolutionary algorithms (EAs) have been increasingly, and successfully, applied to
combinatorial optimization problems. However, EAs are relatively complicated algorithms …

This paper presents an experimental study of NK landscapes with the main focus on the
relationship between (1) problem parameters,(2) various measures of problem difficulty of …

Empirical studies have shown that the overall performance of random bit climbers on NK-
Landscapes is superior to the performance of some simple and enhanced GAs. Analytical …

The neutral theory of evolution suggests that most mutations do not cause a phenotypic
change. In this case the mapping from genotype to phenotype contains redundancy such …

In recent years, not only ruggedness but also neutrality has been recognized as an
important feature of a fitness landscape for genetic search. Following that the concept of …
