Unformatted text preview: 1. Convert the following linear programming problem to standard form and then write out the coefﬁcient matrix A. Maximize 33:1 — x2 + 4 subject to IV ._\ \$1 — \$2 —2IE1 + 3:172 901 S 2, 902 free 2. Consider the linear programming problem below (in standard form). (a) Write the basic feasible solution corresponding to the basis {\$2,533}. (b) Perform the Optimality Test of the Simplex Method to determine whether the basis {\$2,353} is optimal. Minimize z = —3x1 —— 5392 + x3 subject to 4171 + 3.112 + \$4 = 2 —2\$2 + \$3 + \$5 \$171,332, \$3,x4,\$5 Z 0 || ._.. 3. Consider the primal linear programming problem in canonical form below. (a) Show that x = (1,1,1,2)T is a feasible solution to the problem. (b) Label each of the constraints of the problem as active or inactive for the feasible solution a: = (1,1,1,2)T. (0) Determine all values of a such that the vector p = (—1,1,1,a)T is a feasible direction at the feasible solution x = (1, 1, 1, 2). (d) Write the objective function of the dual linear programming problem, but no other part of that problem. (Note that part ((1) has nothing to do with any other part of this question.) ...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
