English term or phrase: deme
Definition from Hypermedia Glossary Of Genetic Terms:
A locally interbreeding population.

Example sentence(s):
  • Basically, the virtual world where migrations take place is constituted by a matrix of demes. Each deme has its own environmental characteristics according to the input files. Splatche
  • Key components of this simulation model include: (i) a three layer intra-deme population structure: hunter-gatherers, non-dairying farmers and dairying farmers. (ii) Population genetic simulation of a LP allele under selection, and an undrifted allele signifying general genetic background. (iii) Intra and inter-deme gene flow and sporadic longer distance migration (following a Gaussian random walk process). UNIVERSITY COLLEGE LONDON
  • The application of the island model is limited because it does not in fact contain explicit geography: migrants are equally likely to have come from any deme in the population. Oxford Journals

Definition from Petr Pošík:
Vícekmenové paralelní genetické algoritmy (Multi-deme PGA)

V tomto modelu je využito již o něco složitější myšlenky. Populace je rozdělena do několika subpopulací, neboli kmenů, které se vyvíjejí izolovaně od ostatních a příležitostně si mezi sebou vymění některé ze svých chromozomů [Grefenstette1981]. Rozdělení na kmeny lze považovat za tak úplné, že na každý kmen lze pohlížet jako na zcela samostatný genetický algoritmus.

Example sentence(s):
  • V globálním modelu probíhá selekce i reprodukce v rámci celé populace, zatímco u vícekmenových PGA berou genetické operátory v úvahu jen jedince v rámci kmene. - Paralelní Genetické Algoritmy
