Assuming that our functional takes exactly this value, the inequality (92) for n → ∞ becomes ϕ1 x1 + + 1 2k t1 1 p + k A1 x1 + a1 2k 1 1 2k (93a) ψ (t) + k D(t)x (t) + B(t)u (t) − t0 ≤ ϕ1 (x1 ) + + 2 t1 1 p + k (A1 x1 + a1 ) 2k 1 2 d x (t) dt dt (93b) 2 (93c) ψ (t) + k D(t)x(t) + B(t)u(t) − t0 d x(t) dt 2 dt, (93d) for all x1 , x(·), u(·). For other possible values of this functional at ψ (·), x , u , the left-hand side of (93) can only get decreased and, hence, the inequality will be strengthened and will remain valid.

Finally, the theorem is proved. Thus, the global numerical process (57)–(59) takes place simultaneously in the functional and finite-dimensional spaces. The control functions, state and adjoint trajectories are moving in functional spaces, while a free right-hand end point of the state trajectory is being iteratively transformed in finite-dimensional space. The process has a weak limit point which is the solution of the original system. The primal and dual functional components of this limit point form a saddlepoint of the augmented Lagrangian (48), its primal and dual vector components produce a saddlepoint of finite-dimensional augmented Lagrangian (96).
