WebbThe procedure for starting "ill-behaved" LPs with (=) and (≥) constraints is to use artificial variables that play the role of slacks at the first iteration, and then dispose of them legitimately at a later iteration. Two closely related methods are introduced here: the M-method and the two-phase method. 1. M-Method.
