Problem 5: Implement the steepest descent method with the backtrack line search (that is, Algorithm 3.1) to minimize the Rosenbrock function Set -1, -0.95 and c-10-4 and the initial point 20-(-1.2, 1)T, Terminate the algorithm once Vf(rk) 10-4. Report the objective function value f, the step length a and the norm of Vf of the last 10 iterations
