# Evolutionary Computation
> **Machine-Evolution Nexus:** [[articles/Digital Darwinism and the Invisible World of Machine Evolution|Digital Darwinism and the Invisible World of Machine Evolution]] places this node within the history and governance of substrate-independent evolution.
**Domain:** Computation / Optimization / Evolution
**Doc Type:** Canonical Wiki Node
**Maturity:** Developed
## Definition
Evolutionary computation is a family of population-based methods using variation, evaluation, selection and inheritance to search or adapt.
## Nexus Context
It includes genetic algorithms and genetic programming but differs from open digital ecology when humans fix the representation, objective and reproduction schedule.
## Evidence Boundary
The methods instantiate selected evolutionary mechanisms; they do not automatically create organisms, open-ended evolution or legitimate objectives.
