For example, x + y ≤ 100 becomes x + y + s1 = 100, whilst x + y ≥ 100 becomes x + y − s 1 + a1 = 100. The artificial variables must be shown to be 0. The function to be maximised is rewritten to include the sum of all the artificial variables.

The simplex solution approach relies on choosing an initial B matrix, and then interactively making improvements. Thus, we need to identify how the solution changes when we change the B matrix. First, let us look at how the basic solution variable values change.

WebbUnbounded solution: When you are searching the outgoing variable whether you notice that every variable in the incoming variable column have all their elements negative or void, it's a problem which has an unbounded solution. So there is no optimal concrete value.
