Transposition
 
The transposable elements (also called transposons) of Gene Expression Programming (GEP) are fragments of the genome that can be activated and then jump to another place in the chromosome. In GEP there are three kinds of transposable elements:
  • Short fragments with a function or terminal in the first position that transpose to the head of genes except the root (insertion sequence elements or IS elements).
  • Short fragments with a function in the first position that transpose to the start position of genes (root IS elements or RIS elements).
  • Entire genes that transpose to the beginning of chromosomes.

Consequently, GeneXproTools 4.0 has three different kinds of transposition:
