Remember to use Anstee's rule: Choose the entering variable with the largest positive coefficient. If there is a tie, then choose the one with the smaller subscript. If there is a choice of leaving variable, then choose the one with the smallest subscript. 5. 3 marks Consider a general feasible dictionary. z V +=1 Cjl; Inti bi -&j=1 dijli i = 1, 2, ...,m in which 21, ... In are non-basic and In+1, ..., In+m are basic. [Notice that here z = v+211 C;X; is the objective function.] Prove that if we can choose an entering variable, but there are no leaving variables, then the objective function can be made arbitrarily large and so the problem is unbounded.
