| Fitness landscape: A Fitness landscape in biology and evolutionary theory is an abstract three-dimensional surface where each point represents a possible genotype and the height of the point represents the fitness of that genotype. A typical problem is that if a local maximum does not represent the optimum, this local maximum can only be left by losses. This is because an organism must first enter a sink in order to move to another maximum._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Peter Norvig on Fitness Landscape - Dictionary of Arguments
Norvig I 155 Fitness landscape/Norvig/Russell: Work by Sewall Wright (1931)(1) on the concept of a fitness landscape was an important precursor to the development of genetic algorithms. >Optimization, >Genetic algorithms, >Local minima, >Search algorithms. In the 1950s, several statisticians, including Box (1957)(2) and Friedman (1959)(3), used evolutionary techniques for optimization problems, but it wasn’t until Rechenberg (1965)(4) introduced evolution strategies to solve optimization problems for airfoils that the approach gained popularity. 1.
