WebbAlgebra and the Simplex Method A linear programming problem (LP) is an optimization problem where all variables are continuous, the objective is a linear (with respect to the decision variables) function , and the feasible region is deﬁned by a ﬁnite number of linear inequalities or equations. LP1 is possibly the best known WebbHowever, the Simplex Method has its own deficiencies. For example, it requires that all variables be non-negative (³ 0); also, all other constraints must be in £ form with non …
