Abstract
The convergence properties of the Davidon-Fletcher-Powell method when applied to the minimization of convex functions are considered for the case where the one-dimensional minimization required at each iteration is not solved exactly. Conditions on the error incurred at each iteration are given which are sufficient for the original method to have a linear or superlinear rate of convergence, and for the restarted version to have ann-step quadratic rate of convergence.
