Linear optimization: Pivot selection rules 1

Theory

The Pivotelement is a spefific element in the Simplex-Tableau. To find an optimal solution for linear problems this kind of tableaus can be used. While a linear problem is given the Simplex-Tableau helps to determine unknown variables with the objective of maximizing a preexisting function f. For solving this problem the tableau is renewed based on the Pivotelemnt as long as the solution is not optimal.
