Pseudospectral Theory Powers DIDO
DIDO’s foundation is pseudospectral theory and is the only pseudospectral solution with mathematically proven convergence properties. But DIDO is fast and easy – absolutely no knowledge of the underlying pseudosprectral theory is required to generate and validate optimal control results.
DIDO provides an opportunity to test theories in the lab environment in record time. Researchers have broadened perspective and can solve problems faster. Problems that could take months to solve with other methods can be solved in a matter of hours with DIDO software.
The input is nothing more than the problem formulation. This generality allows for:
A Minimalist Approach to Solving Optimal Control Problems
DIDO automatically outputs:
Use the outputs alongside classical tools like Pontryagin’s Principle to instantly verify numerical results.
SEE IT FOR YOURSELF
All DIDO needs is the problem formulation in a manner ... prescribed in a manner that is nearly identical to writing it on a piece of paper. DIDO’s unique pencil-and-paper-like approach to problem coding is made possible through the use of DIDO's unique expressions.
DIDO IS THE FIRST OPTIMAL CONTROL THAT IS PACKAGE:

[cost, primal] = dido(Problem) Problem is a structure array with fields cost, dynamics, events and path that point to the input files, Problem.cost = `MyCostFile’; Problem.dynamics = ‘MyDynamicsFile’; Problem.events = ‘MyEventsFile’; Problem.path = ‘MyPathFile’; The variable, primal, is used in nearly all DIDO files to pass the states, controls, parameters and other useful quantities; thus, for example, primal.states primal.controls carry with them the state- and control-trajectory.
This generality allows for:
