If ψis nondecreasing, the primal formulation (P) can be simplified—it is equivalent to the unconstrained problem (U) −w TLg +s Ψ(g)+J(−Pg) = min g! Convex functions are allowed to attain +∞ as a value; the domain, domΦ, is the set where Φ is finite. We assume that all convex functions in (P) and (U)
