Abstract

In this paper, we analyze the global convergence of the least-change secant method proposed by Dennis and Wolkowicz, when applied to convex objective functions. One of the most distinguished features of this method is that the Dennis-Wolkowicz update doesn't necessarily belong to the Broyden convex family and can be close to the DFP update, but it still has the self-correcting property. We prove that, for convex objective functions, this method with the commonly used Wolfe line search is globally convergent. We also provide some numerical results.
