Nine SIMPLEX TABLEAUS are shown. Remember that the pivot column is the column containing the most negative indicator; occasionally there is a tie for most negative indicator, in which case: flip a coin. If there is no negative indicator, either the tableau is a FINAL TABLEAU or the problem has NO SOLUTION. Exercises and help in finding the indicator row are available.
