'''Gene expression programming (GEP)''' in [[computer programming]] is an [[evolutionary algorithm]] that creates computer programs or models. These computer programs are complex [[tree structure]]s that learn and adapt by changing their sizes, shapes, and composition, much like a living organism. And like living organisms, the computer programs of GEP are also encoded in simple linear [[chromosome]]s of fixed length. Thus, GEP is a [[Genotype–phenotype distinction|genotype–phenotype system]], benefiting from a simple [[genotype|genome]] to keep and transmit the genetic information and a complex [[phenotype]] to explore the environment and adapt to it.
