Ant colony algorithm is adopted to select the center of RBF network,It combines the distributed computing, positive feedback mechanism and greed search algorithm. In the search process, it is easy to obtain the global optimization and it has the shorter search time. In eddy current nondestructive detecting,the simulation shows that the construction of RBF network is optimized and the convergence and precision are improved.
