- Abstract:
-
The authors reviewed basic principles of gene expression programming (GEP). On that basis, an improved GEP algorithm, or IGEP, was created, based on a dynamic mutation operator. The dynamic mutation operator changed with the gene number of the genome and the number of evolutionary generations. The complexity and convergence properties of the algorithm were investigated. The new IGEP was used to predict stockmarket indexes. Simulation results indicated that the IGEPbased model is more accurate than the classical GEPbased model.
