Consider the primal-dual pair of optimization problems
$$ egin{gathered} Min leftlangle {c,x}
ight
angle {
m M}ax leftlangle {b,y}
ight
angle hfill \ (P) s.t. x in K s.t. z in K* (D) hfill \ Ax = b A*y + z = c hfill \ end{gathered} $$
where
X and Y are Euclidean spaces with dim X ≥ dim Y.
A : X → Y is a linear operator, assumed to be onto.
A* : Y → X is its adjoint.
K is a closed, convex, facially exposed cone in X.
K* := {z|〈z,x〉≤ 0 ∀x∈K} is the dual of K, also a closed, convex, facially exposed cone.
