Question 4.Derive necessary and sufficient condition(s) for a pair (w, b) to be aglobal optimal solution. Is such a point is a strict global solution? Give a brief explanation?Find a formula for the optimal solution. Given a dataset D = {(z,y), i=1,2,...,m} consisting of m predictors x = =(Ti,..., Tin) €R" and m corresponding responses y, E R. Consider the following linear ridge regression model:(P)minimize J(w, b, x):=m;Σ((x₁, w) + b - y)² + (|||| +8²)i=12mwhere (w, b) ER" x R is a vector of parameters to be determined and A> 0 is a penaltyparameter to be tuned for finding the best regression function.

nts in Page 348 This theorem simplifies the job of finding an optimum value. First, graph the feasible region and find all corner points. Then test each point in the objective function. Finally, identify the corner point producing the optimum solution. With the theorem, the problem in Example 1 could have been solved by identifying the five corner points of Figure 7.16: (0, 1), (0, 2), (.5, 2.25), (2, 0), and (1, 0). Then, sub- stituting each of these points into the objective function z = 2x + 5y would identify the corner points that produce the maximum and minimum values of z. Corner Point (0, 1) (0, 2) (.5, 2.25) (2,0) (1, 0) 2(0)+ 5(1) = 5 2(0)+ 5(2) = 10 2(.5) + 5(2.25) = 12.25 2(2) + 5(0) = 4 2(1) + 5(0) = 2 Value of z = 2x + 5y 348 ■ (maximum) From these results, the corner point (.5, 2.25) yields the maximum value of 12.25 and the cor- ner point (1, 0) gives the minimum value of 2. These are the same values found earlier. A summary of the steps for solving a linear programming…
(a) Let x be the order quantity and r the number of orders placed during the year. Find the inventory cost (ordering cost plus carrying cost) in terms of x and r. B. (b) There are r orders of x packages in a year. Therefore, there are r times x packages ordered in a year. Therefore, the constraint equation is____ (c) To find the minimum value of C, use the first derivative test to locate the extreme point. Find the expression for Upper C prime.
