In order to increase the diversity of population, MFCMGA uses idiotypic immune network theory to improve the selection operator of SGA. Meanwhile in order to decrease the randomicity of SGA, the crossover probability, crossover position and mutation probability are adjusted dynamically by using fuzzy inference, which is based on analyzing the heuristic fuzzy relationship between algorithm performance and evolutionary parameters from the viewpoints of environment, population, individual and gene.

Finally, taking these dates and using it as the functions of genetic program, and using the standard arithmetic operation as the terminals of GP. The object in this algorithm is the chiller consumption energy. Through the option of GP which contains 'crossover'、 'reproduce' and 'mutation' to iterant compute the population is composed of functions and the terminals of GP. Finally, we would find the consumption energy model of chiller.
