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 A measure of an individual's ability to survive and reproduce; the chance that an individual will leave more offspring in the next generation than other individuals.
fitness
The genetic contribution of an individual to succeeding generations relative to the contributions of other individuals in the population.

Fitness: The ability to survive to reproductive age and produce viable offspring. Fitness also describes the frequency distribution of reproductive success for a population of sexually mature adults.
Fitness A measure of an organism's or a genotype's ability to leave offspring in the next generation.
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.
Fitness
Also called adaptive value. The relative reproductive success of a genotype as measured by survival, fecundity or other life history parameters. See Darwinian fitness and natural selection.

fitness Degree of adjustment and suitability for a particular environment.
Fitness is a measure of an individuals ability to survive and reproduce. Those with the highest fitness are more likely to survive and reproduce. Thus, they make a greater contribution to the gene pool, of the next generation than do those less "fit".
Fitness-proportionate selection: More fit individuals are more likely, but not certain, to be selected.
The measures of fitness include survival due to adaptive traits both physiological and behavioral. An example of fitness is the differential survival of the black and white moth variants in the forests outside big cities.
The Measure of "Fitness"
Fitness is a measure of reproductive success. Those individuals who leave the largest number of mature offspring are the fittest. This can be achieved in several ways: ...

Adaptation: a condition or character which afford fitness to a species in a particular environment. Adaptive radiation: evolutionary divergence of members of a single phyletic line into many different niches.
The Genome Data Base (GDB) underwent a fitness test at the Eleventh International Workshop on Human Gene Mapping (HGM 11) and came through as a solid and reliable tool for the scientific community.
In population genetics the evolution of a population of organisms is sometimes depicted as if travelling on a fitness landscape. The arrows indicate the preferred flow of a population on the landscape, and the points A, B, and C are local optima.
Selfish DNA
A DNA sequence that does not contribute to the fitness of an organism but is maintained in the genome because it promotes its own replication.

This is because they are the least able to tolerate mutational change without substantially reducing the fitness of the individuals that harbor them. Many of these very conserved genes play a role in development.
