Genetic algorithm terminology.

Terminology	Definition
Gene	A single value representing a parameter of a potential solution
Chromosome	A vector representation of the parameters of a potential solution
Population	A collection of chromosomes
Crossover	A process by which two or more existing chromosomes are recombined to yield two different chromosomes
Mutation	A process by which gene values are changed yielding a new chromosome
Selection	A process that determines which chromosomes from the population to use for the crossover process
Fitness function	Algorithm that assigns a value or “fitness” to each chromosome This value being typically minimized or maximized
