The author considers an extension of quasi-Newton algorithms obtained by using some specific nonquadratic polynomial models in order to approximate a nonlinear cost. No theory of convergence is given. Instead, the author gives numerical experiments that show a modest advantage of the new method with respect to the classical BFGS algorithm.
