On the convergence rate of the Cauchy algorithm in the l2 norm

This paper presents a convergence rate for the sequence generated by the Cauchy algorithm. The method is applied to a convex quadratic function with exact line search. Instead of using the norm induced by the hessian matrix, the q-linear convergence is shown for the l2 (or Euclidean) norm. Citation Tecnhical Report, Dep. Mathematics, Federal University … Read more
