Problem 3. (20) Use the steepest descent method with linesearch to find the minimum of the function f(x,y) 5x2 + y2. Your program should do the following things a. (12) Implement the algorithm and find the solution. The stopping criterion for the solution should be that the norm of the gradient is bounded by 10-6 The program should include a linesearch that finds the minimal function value along the search direction for nsearch equally spaced points in (0,1], where nsearch is a small number, say no larger than 20. You may want to experiment with this number b. (5) Produce a contour plot of the level curves of the function. This plot should be drawn to scale on the region -4
