Math 132A Assignment 5

1. Apply the Quasi-Newton method with the SR1 update formula to locate the minimizer of

Start with and B0 = I. At each step calculate the optimal step size.

Just determine the first two iterates x(1) and x(2) (unless you want to do more!)

2. Same as Question 1 but now use the BFGS update formula instead.

3. Same as Question 1 but now use the Conjugate-Gradient Method (do three steps this time so you get the actual solution!)
