Professor Jay Liu invites you to attend the Masters Thesis defense of Subrat Pathak next Friday, May 10th at 11:00 am in GAB 461. Cookies and coffee will be served in GAB 472 following this event. "Non Linear Conjugate Gradient Methods" Abstract: We look into the development of techniques to solve unconstrained minimization problems for nonlinear functions. In particular the theory and development of nonlinear conjugate gradient methods from conjugate directions and the performance of Fletcher Reeves and Polak Ribiere methods when applied to Rosenbrock function.
