On the international level this presentation has been inspired from (Bryson & Ho 1975), First, because a time-dependent per-formance criterion can be posed, the goal of the motor task can be included in the formulation of the problem. The type of model analysed in that chapter involved agents making choices concerning the values of a variable at an instant in time.Many choices, however, involve the time-paths of variables from now, when the choice is made, until some time in the future. In contrast, in a dynamic setting, time enters explicitly and we encounter a dynamic optimization problem.
