Global convergence of the Fletcher-Reeves algorithm with inexact linesearch. (English) Zbl 0834.90122
Summary: We investigate the convergence properties of the Fletcher-Reeves algorithm. Under conditions weaker than those in a paper of M. Al-Baali, we get the global convergence of the Fletcher-Reeves algorithm with a low-accuracy inexact linesearch.
