Otherwise there would be multiplied by "-1" on both sides of the inequality (noting that this operation also affects the type of restriction).In the previous part we implemented and tested the simplex method on a simple example, and it has executed without any problems. In the first part, we have seen an example of the unbounded linear program.In general, there might be longer runs of degenerate pivot steps.

If we move any more than 8, we're leaving the feasible region.

Therefore, we have to move the smallest distance possible to stay within the feasible region.

The variable in that column will be the basic variable for the row with the non-zero element. Hopefully your answer is to gain $40 for each step you move.

That's a little confusing, so maybe this will help. If it isn't you're not going to comprehend the simplex method very well.

If one of the ratios is 0, that qualifies as a non-negative value. Place an arrow next to the smallest ratio to indicate the pivot row.

The variable that is basic for the pivot row will be exiting the set of basics.

If there are no negatives in the bottom row, stop, you are done.

A positive value in the bottom row of the tableau would correspond to a negative coefficient in the objective function, which means heading in that direction would actually decrease the value of the objective.

The values of all non-basic variables (columns with more than one number in them) are zero. Each row of the tableau will have one variable that is basic for that row.

Which variable that is can be determined fairly easily without having to delete the columns that correspond to non-basic variables.
