The jamming resource allocation in electronic warfare is a typical combinatorial optimization problem, and is also a NP-hard problem.Besides the typical mathematical programming approaches, all kinds of intelligent optimization methods have been widely used in recent years too. In this paper, the jamming resource allocation mathematic model and its typical solving framework are firstly introduced. Taking the genetic algorithm, immune algorithm, evolutionary computation, particle swarm optimization algorithm, ant colony algorithm, and the various improved methods as typical examples, a review is made to the research progresses of application of such intelligent optimization methods in jamming resource allocation problem. The main points of the application of each method are summarized with its development status.It can be taken as a reference for the engineering application of each method, and for the research of artificial intelligence in electronic warfare.
