Give a brief answer to each of the following questions about the outcomes and properties of LPs: Degeneracy: In a 2 variable problem, what does it look like on a graph? How do you identify it in a tableau? Multiple Optimal Solutions: How do you identify it in a tableau? How is this different from the case of a unique optimal solution? From an optimal tableau, how do you find an alternate optimal solution (actual variable values?) Can you have exactly 2 optimal solutions? 3? Why?
