History of Tunisia for centuries assigned its foundation to a queen of Tyre, Elissa, also called Dido. The Roman historian Pompeius Trogus, a near contemporary of Virgil, describes a sinister web of court intrigue which caused Queen Elissa (Dido) to flee the city of Tyre westward with a fleet of ships. The Roman poet Virgil (70–19 B.C.) portrays Dido as the tragic, admirable heroine of his epic the "Aeneid", which contains many inventions loosely based on legendary history, and includes the story about how the Phoenician queen acquired the Byrsa. By the middle of the sixth century B.C., Carthage had grown into a
DIDO (software) to maneuver the International Space Station to perform the zero-propellant maneuver. Since this flight demonstration, DIDO was used for the International Space Station and other NASA spacecraft. It is also used in other industries. DIDO is also available as a MATLAB "toolbox" product. It does not require the MATLAB Optimization Toolbox or any other third-party software like SNOPT or IPOPT or other nonlinear programming solvers. The MATLAB/DIDO toolbox does not require a "guess" to run the algorithm. This and other distinguishing features have made DIDO a popular tool to solve optimal control problems. The MATLAB optimal control toolbox has been
