In this paper, a new random search method Ras Val for Neural Networks (NN) learning is proposed. RasVal (Random Search with Variable Search Length) is a kind of random search and it can find a global minimum instead of a local minimum using the capability of intensified and diversified searches. The main different point of RasVal from commonly used Random Search Methods (RSM) is that the shape of the probability density function for random searching can be adjusted based on the information of success or failure of the search. First, RasVal is described and after that, performance between RasVal, Back Propagation Method (BP) and Back Propagation Method with momentum (Mom. BP) are compared. The performance is evaluated by the simulations which include both static and dynamic Neural Networks (NN) learning problems. In the simulations, NN is trained to realize nonlinear functions and to control a nonlinear crane system by using RasVal, BP and Mom. BP. Simulation results show that Ras Val is superior or nearly equal to BP and Mom. BP because of the ability of intensification and diversification of the search.
