Few research studies have been conducted to improve the prediction ability of the GP ( Genetic Programming ) and the MGGP ( Multi-Gene Genetic Programming ) models by hybridising them with the other potential computational intelligence methods such as artificial neural network ( ANN ) , fuzzy logic , M5 ’ regression trees and support vector regression .
