Abbreviations
- Evolutionarily stable equilibria (ESS):
-
An ESS is a set of frequencies of different types of individuals in a population that can not be invaded by the evolution of a single mutant. It is the evolutionary counterpart of a Nash equilibrium.
- Fitness landscape:
-
A metaphorical description of fitness as a function of individual's genotypes or phenotypes in terms of a multivariable function that does not depend on any external influence.
- Genetic locus:
-
The position of a gene on a chromosome. The different variants of the gene that can be found at the same locus are called alleles.
- Nash equilibrium:
-
In classical game theory, a Nash equilibrium is a set of strategies, one for each player of the game, such that none of them can improve her benefits by unilateral changes of strategy.
- Scale free network:
-
A graph or network such that the degrees of the nodes are taken from a power-law distribution. As a consequence, there is not a typical degree in the graph, i. e., there are no typical scales.
- Small-world network:
-
A graph or network of N nodes such that the mean distance between nodes scales as \({\log N}\). It corresponds to the well-known “six degrees of separation” phenomenon.
