In 1954 he began his work on optimal control.

It gives an example application to optimal control in queueing networks.

If is the optimal control for the problem, then the principle states that:

More general conditions on the optimal control are given below.

For severe asthma, it has been estimated that the savings produced by optimal control would be around 45% of the total medical costs.

The time required to achieve optimal control of symptoms is highly variable, and may take several months or longer.

A number of these techniques have been inspired from ideas in optimal control.

The theory of optimal control is concerned with operating a dynamic system at minimum cost.

More recently the same idea has been taken into the theory of optimal control.

Thereby the weapons serve as training devices for reaching optimal control of body and mind.
