Hailed as a breakthrough software, DIDO is based on the pseudospectral optimal control theory of Ross and Fahroo. DIDO utilizes trademarked expressions and objects that facilitate a user to quickly formulate and solve optimal control problems. Rapidity in formulation is achieved through a set of DIDO expressions which are based on variables commonly used in optimal control theory. For example, the state, control and time variables are formatted as: The entire problem is codified using the
