✦ Synopsis
This paper presents an improved approximation technique for gradient based approximation methods of mathematical programming. The proposed technique prevents oscillations of the sequence of approximate solutions in the optimization process eciently and preserves the relatively simple form of the approximating functions. The improvement is achieved by adding an appropriate convex term to each conventional approximating function. The theory is illustrated with several numerical examples.
