Abstract: Artificial immune system is the computing system based on the theory of natural immune, and the multi-objective optimization is an important researching direction in optimizing field. The study found that all kinds of immune algorithms operational principles and process are not same. This paper presented a method that can unify the expression of the multi-objective optimization immune algorithm,and abstracted the main principle and operational process of three kinds core operators of the immune algorithm. This core operator can express classic immune algorithms NNIA and CMOIA. It is proved that this three immune operators are feasible and efficient to express algorithms.
