Linear Programming

What are some examples of personal or professional decisions where constrained optimization might be applied? You don't have to formulate the mathematical problem, just discuss what the decision variables would be, how would you measure success (i.e., what would you maximize or minimize), and what conditions might the decision ...continues

Simplex Method

Consider the following maximum problem in standard form: Maximize Z = 8X1 + 2X2 + 3X3 subject to the constraints X1 + 3X2 + 2X3 < 10 4X1 + 2X2 + 3X3 < 8 X1 > 0, X2 > 0, X3 > 0 (a) Rewrite the two constraints as equations by adding slack variables S1 and S2. (b) Set up the initial simplex tableau for t ...continues
