  In this paper we deal with the numerical solution of the mixed fourth order boundary value problem by coupling the optimization algorithm and localized RBFs collocation method.To formulate the problem as an optimization one,we first construct the constraints functions by splitting the biharmonic equation into two coupled Laplace equations.Then,the Neumann boundary condition is used as energy-like error functional to be minimized.The effectiveness of the proposed method is demonstrated by solving examples.
