This article investigates two aspects of the generalized Broyden quasi-Newton method that have a major impact on its convergence: the initial approximation of the Jacobian and the presence of nonlinearities in the secant conditions. After reformulati

Publikováno v: COMPUTATIONAL OPTIMIZATION AND APPLICATIONS

In optimization, one of the main challenges of the widely used family of Quasi-Newton methods is to find an estimate of the Hessian matrix as close as possible to the real matrix. In this paper, we develop a new update formula for the estimate of the
