Using the nonlinear programming (steepest decent) method, we want to estimate the parameters of an
ARMAX model whose polynoomials are given in the following.
A(q¹)=1+qq¹ + a₂q² + a₂q³
v(1)
B(q¹)=bq¹
C(q-¹)
C(q) = 1+q₁q¹ +c₂q²
u(t)
y (t)
B (q¹)
A(g-¹)
a) What is the minimum number of the observations?
b) Assume that we have some parametric observations as
U
=[u(1),u(2),u(3),u(4),u(5),u(6),u(7),u(8)]
Y = [y (1),y (2),y (3),y (4), y (5),y (6),y (7), y (8)
Considering whole steps of the mentioed method such as initial selection and updating of the parameters'
value (two updating steps is sufficient without considering the initialization step), write all the necessary
relations and parameters in respect to the obserations in a parametric and simplified form as possible.

Exercise 2. Here is a classic geometric problem, in the same application domain as the Center Selection problem: Given n points with Cartesian coordinates (₁, 3) in the plane, and positive weights w, find one(!) point (x, y) that minimizes the weighted sum of the Euclidean distances to the given points. For formal clarity: We want to minimize n Σwi i-1 n •√(x- i-1 (x − x)² + (y - y₁)². This problem is at least not very easy to solve exactly. In the following we therefore propose a rough but rather quick and simple approximation algorithm: Instead of the Euclidean distance, take the Manhattan distance and minimize 1 w₁(x − x₂|+|y-yil). 2.1. Explain how the point that minimizes the weigthed sum of Manhattan distances can be found in polynonial time. That is: Sketch an algorithm, argue why it is correct, and explain your time bound. Try to keep the time bound as low as possible. 2.2. Show that this algorithm has an approximation ratio √2. More specifi- cally: The point found by the…
