Unformatted text preview: x 6 as entering variable. Do you see a pattern? Explain how the simplex method could cycle in twelve iterations, starting from the tableau above. What would happen if you used the smallest subscript rule? 3. The following claims concern a single pivot of the simplex method, from a current tableau to a new tableau. State whether each claim is true or false. Justify your answers: if you state a claim is true, explain why; if you state it is false, give an example illustrating that it can fail. (i) After a degenerate pivot, the new tableau must be degenerate. 1 (ii) Starting from a degenerate current tableau, any pivot must be degenerate. (iii) If the new tableau is degenerate, the pivot must have been degen-erate. (iv) A degenerate pivot must start from a degenerate current tableau. 2...
