EE364a Homework 3 solutions - Stanford Engineering …
All feasible solutions are optimal. • The problem is feasible, and c is not in the range of AT (ˆc 6= 0). The problem is unbounded (p⋆ = −∞). To verify this, note that x = x 0 −tˆcis feasible for all t; as t goes to infinity, the objective value decreases unboundedly. In summary, p⋆ = +∞ b ∈ R(A) λTb c = ATλ for some λ
