Many actual situations can be represented in a realistic manner by the two-stage stochastic nonlinear programming problem MinxEmin y[φ (x)+ψ (y)] subject to g(x)+h(y)≥ b, where b is a random vector ...

Conditions which are necessary and sufficient for convergence of a nonlinear programming algorithm are stated. It is also shown that the convergence conditions can be easily applied to most ...
