WebbThe basic is a variable that has a coefficient of 1 with it and is found only in one constraint. If there are no basis variables in some restriction, then we add them artificially, and artificial variables enter the objective function with the coefficient -M if the objective function tends to max and M, if the objective function tends to min. Webb2 The Simplex Method In 1947, George B. Dantzig developed a technique to solve linear programs this technique is referred to as the simplex method. 2.1 Brief Review of Some Linear Algebra Two systems of equations Ax= band Ax = bare said to be equivalent if fx: Ax= bg= fx: Ax = bg.
