Definition 2 A linear program (LP) is feasible if there exists a feasible solution, otherwise it is said to be infeasible. Definition 3 An optimal solution x∗ is a feasible solution s.t. cT x∗ = min{cT x : Ax = b, x ≥ 0}. Definition 4 LP is unbounded (from below) if ∀λ ∈ R, ∃ a feasible x∗ s.t. cT x∗ ≤ λ.
