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. WebbSTEP 3 For the starting basic solution; use the artificial variables in the basis. Now the starting table in the simplex. procedure should not contain the terms involving the basic …
