What is Simplex Method: Handling Artificial Variables about?

The document discusses two standard methods for handling artificial variables in the simplex method: the two-phase simplex method and the big-M method. It defines an artificial variable as a non-negative variable temporarily added to obtain an initial basic feasible solution, which must then be driven to zero. The simplex algorithm moves between basic feasible solutions at each iteration, choosing a leaving variable and entering variable to pivot based on ratio tests to increase the objective function value
