Webb10 feb. 2016 · IntroductionGraphical methods are fine for 2 variables.But most LP problems are too complex for simple graphical procedures.The Simplex Method:examines corner points, like in graphing;systematically examines corner points, using algebra, until an optimal solution is found;does its searching iteratively. 6-* Webb1 aug. 2024 · Begin the simplex algorithm simplex with the current basis B and current ( x, y). If the algorithm terminates before an artificial variable is eliminated: If the cost is zero, STOP. The problem is feasible, but extra steps need to be taken to drive the remaining artificial variables out of the basis. See Section 3.5 for details.
