(EC,
biol) A mixed
POPULATION.
A population in which any
INDIVIDUAL
may be mated with any other individual with a probability which depends only on
FITNESS.
Most conventional
EVOLUTIONARY ALGORITHMs
have
PANMICTIC POPULATIONs.
The opposite is a population divided into groups known as
SUB-POPULATIONs,
where individuals may only mate with others in the same sub-population. cf
SPECIATION.
An
INDIVIDUAL
which takes part in
REPRODUCTION
to generate one or more other individuals, known as
OFFSPRING,
or children.
cf
FITNESS.
The expressed traits of an
INDIVIDUAL.
Refers to a
POPULATION
of organisms. The life span of a population of organisms from pre-historic times until today. cf
ONTOGENESIS.
Notation originally proposed in
EVOLUTION STRATEGIEs,
when a
POPULATION
of "mu"
PARENTs
generates "lambda"
OFFSPRING
and all mu and lambda
INDIVIDUALs
compete directly, the process is written as a (mu+lambda) search. The process of competing all
parents and offspring then is a "plus strategy." cf.
COMMA STRATEGY.
A group of
INDIVIDUALs
which may interact together, for example by mating, producing
OFFSPRING,
etc. Typical
POPULATION
sizes in
EC
range from 1 (for certain
EVOLUTION STRATEGIEs)
to many thousands (for
GENETIC PROGRAMMING).
cf
SUB-POPULATION.
