Document Summary
Go back to original problem and pivot basis cbk final tableau in arex problem had these in basis p x x t so o. 22 no solution to this equation not possible to satisfy all constraints in the original problem cine problem infeasible. 2 positive entry in xl column this corresponds to unbounded problem. Write a dictionary from here a army from. Idea can choose 43 0 and x very large which makes 2 large and. Ast got z3e co zt is or so z b unbounded cno max. Bland"s rule there is a tie in s. n. ir. In case of tie in s. mn variable w the the set is leaving the basis. 5 n r algo w to determine plot choose pint lower subscript negate zero rule. Bland"s 1hm l s and bland"s rule does not cycle. Simplex algorithm either a halts after phase 2 w infeasible problem concluded fi halts after phase ii.
