[PDF] Lecture 12 1 Finding an initial basic feasible solution
2 oct 2014 · The corresponding basic feasible solution is x = 0, z = b We use this to initialize the simplex algorithm The simplex method can be one of two possible results (note that the modified LP is never unbounded: since z ≥ 0, the objective function is bounded from below by 0 )
