NEWTON-REGULARIZED METHOD BASED ON A BASIC FUNCTION FOR SOLVING THE INVERSE PROBLEM OF CONVECTION-DIFFUSION EQUATIONS

In this paper, a new iteration algorithm to solve the coefficient inverse problem is described by using a "basic function" which is specially defined and the idea of regularization. The method is simple and clear.The main advantage of the algorithm is that its computing cost is less than other current algorithms, such as PST and Purlerbalion Methods. Since it has uniform scheme, on the other hand, the method can be easily exleded to other kinds of inverse problems of different leal equations, multidimensional inverse problem and multiparameler inverse problems, etc.
