100%
I need answer of q5 that i attached separately I also attached the sample question (5 with answer) U can see it's similar just see this method and solve exactly like this plz I appreciate your efforts plz try to solve this and take a thumb up I need this in 1.30 hour plz plz plz plz help me plz don't reject plz use a matlab exactly like sample
Ans
5. The gradient is p_1 = g = [6,8,40,2,0]^T, and the Hessian is:
[2 0 0 0 0]
[0 2 6 0 0]
[0 6 34 0 0]
[0 0
0 2 0]

[00 002],
We can
so the second direction is p_2 = -B^-1 g = [-3,-1,-1,-1,0] ^T.
assume that the minimizer is at the border of the trust region, and the
result is p = 0.0046*p_1 + 0.1621*p_2= [-0.4587 -0.1253 0.0219 -0.1529
0]^T, giving a minimizer of [0.5413 0.8747 1.0219 0.8471 11^T.
The global minimizer can be found by rewriting f(x) = (x_1+2)^2 - 4 +
(x_2+3x_3)^2 + 8x_3^2 + x^4^2 + (x_5-1)^2 - 1, so that the minimizer is [-
2,0,0,0,1].

s) An objective function model is given by m_k (x) = x_1^2 +
4x 1 + x_2^2 + 17x_3^2 + x_4^2 + x_5^2 + 6x_2x_3 - 2x 5. Find the
two-dimensional subspace minimizer for m_k at x_k=(1,1,1,1,1) with
delta_k= 1/2. What is the global minimizer?
