Overview of Artificial Immune System and Its Algorithms

According to the prototype of living bodys immune system，Artificial Immune System, (AIS) is introduced. Based on the main function of immune system， the typical algorithms are described， such as immune algorithm，negative and clonal selection algorithms，immune evolutionary algorithm，AIS-neural network mix intelligent system，fuzzy immune system，danger model and so on. a chronological list of AIS models and techniques that are found in the literature is showed. Finally，based on the analysis of AIS，the development directions and research emphases are discussed.
