initial basic feasible solution simplex method

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 )

30 sept 2014 · Then x = 0,z = b ≥ 0 is a basic feasible solution The simplex method can have 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) Case 1: The value of modified LP is non-zero
