In general, a linear program will not be given in the canonical form and an equivalent canonical tableau must be found before the simplex algorithm can start. This can be accomplished by the introduction of artificial variables. Columns of the identity matrix are added as column vectors for these variables. If the b value for a constraint equation is negative, the equation is negated before adding the identity matrix columns. This does not change the set of feasible solutions or the opti… WebbObtain optimal solution to the problem by using the simplex method, how much of each type of row material should be used for each unit of the final product in order to minimize the cost?
