Intelligent computing (IC) is a general term for computing techniques developed based on traditional computing methods and different from traditional computing methods. Inspired by the objective laws of biological groups and biological thinking and movement in nature, intelligent computing has developed computing methods in many algorithmic fields such as intelligent computing, including evolutionary computing, group intelligent computing, neural computing and so on. Most of these algorithms realize the purpose of intelligent computing by simulating the special functions of some species in nature or some characteristics of nature, and program and execute the wisdom of biological groups and some natural laws of biological groups, so as to design the optimization algorithm with intelligent nature.
