Fitness landscapes in evolutionary optimization
Apart from the field of evolutionary biology, the concept of a fitness landscape has also gained importance in evolutionary optimization methods such as genetic algorithms or evolutionary strategies.

Fitness
: Lifetime reproductive success of an individual (i.e., the total number of offspring who themselves survive to reproduce). It can be seen as the extent to which an individual successfully passes on its genes to the next generation.
