4.2 Write a program that implements the dogleg method. Choose Bi to be the exact Hessia. Apply it to solve Rosenbrock's function (2.22). Experiment with the update rule for the trust region by changing the constants in Algorithm 4.1, or by designing your own rules. 4.2 Write a program that implements the dogleg method.
