Jul 22, 2022 · In this article, readers will gain an insight into artificial variables and the two methods that use them to extend the simplex method to solve LP problems. In the previous …

Artificial variables are introduced in linear programming to convert inequality constraints into equality constraints. In linear programming, the objective is to maximize or minimize a linear …

In this example, there is only one equation with an artificial variable. If there were several equations with artificial variables, we would have to subtract accordingly.

The artificial variables in phase 1 are introduced so that we can make the original problem variables nonbasic and set them to zero even though that may not be feasible to the original …

This article throws light upon the top two artificial variable techniques for solving L.P.P. The techniques are: 1. The Big-M technique. 2. The Two Phase Method. 1. The Big-M Method: …

In Two Phase Method, the whole procedure of solving a linear programming problem (LPP) involving artificial variables is divided into two phases.

In such cases basis matrix cannot be obtained as an identify matrix in the stm1ing simplex table, therefore we introduce a new type of variable called the artificial variable. These variables are …

When there are “≥ type” constraints in the linear programming problem, surplus variables are subtracted from them to transform the problem into the standard form. The equality …

Step 2 – Add non-negative artificial variable to the left side of each of the equations corresponding to the constraints of the type ‘≥’ or ‘=’. When artificial variables are added, it causes violation of …

An artificial variable is a variable introduced into each equation that has a surplus variable. To ensure that we 7 qp consider only basic feasible solutions, an artificial variable is required to …
