An indirect sufficiency proof for problems with bounded state variables
I. Bert Russak · Pacific Journal of Mathematics · 1976
A set of sufficient conditions is obtained for problems involving constraints of the form ψ a (ί, JC) ^ 0 a = 1, , ra.The method of proof is indirect.It is shown by essentially strengthening the first and second order necessary results previously obtained by the author for problems of this type, that a proper strong relative minimum is obtained.1 Unless otherwise noted, the indices i, k, σ, a will have the respective ranges ί = l, ,N, k = 1, , K, σ = 1, , r and a = 1, , m.219
