Linear Programming: Artificial Variable Technique

WebbAs any other variable, artificial variables are included in the objective function but the value attached to them creates another problem. In minimisation problems, since the objective is to find the lowest cost possible, a very large value is allocated to artificial variables. This value is denoted by M where M is a very large positive value.

"Webb9 okt. 2013 · The only way the simplex iterates and leaves the cost unchanged is in the case that cycling occurs; in this case, we remain at the same BFS and thus, the simplex is not moving the feasible solution by a positive distance, or at all. \\ \noindent \textbf { (b)} A variable that has just left the basis cannot reenter in the very next iteration. \\ " - Simplex method with artificial variables
