This paper presents a worldwide optimisation way of fixing common nonlinear programming
problems exposed to box constraints. No matter convexity or nonconvexity, by presenting a
differential flow about the dual achievable hour, a locate of complete methods to the initial difficulty is acquired,
and criteria for global optimality and information on solutions receive. Our theorems improve and
generalize recent known leads to the canonical duality theory. Programs to some class of restricted
optimal control troubles are talked about. Particularly, an analytical type of the perfect control is
expressed. Some good examples are incorporated as one example of this fresh approach. …
