Dido, Queen of Carthage (play) is presumed to have been lost in the 1809 Drury Lane Theatre fire, since nothing of it has survived. An adaptation of the play was broadcast on BBC Radio 3 on 30 May 1993, the 400th anniversary of Marlowe's death, along with "The Massacre at Paris", directed by Alan Drury and Michael Earley and featuring Sally Dexter as Dido, Timothy Walker as Aeneas, Jeremy Blake as Iarbas, Ben Thomas as Achates, Teresa Gallagher as Anna/Juno and Andrew Wincott as Cupid. Dido, Queen of Carthage (play) Dido, Queen of Carthage (full title: The Tragedie of Dido Queene of Carthage) is a
DIDO (software) in solving for the costates in optimal control problems. DIDO generates spectrally accurate solutions whose extremality can be verified using Pontryagin's Minimum Principle. Because no knowledge of pseudospectral methods is necessary to use it, DIDO is often used as a fundamental mathematical tool for solving optimal control problems. That is, a solution obtained from DIDO is treated as a candidate solution for the application of Pontryagin's minimum principle as a necessary condition for optimality. DIDO is used world wide in academia, industry and government laboratories. Thanks to NASA, DIDO was flight-proven in 2006. On November 5, 2006, NASA used DIDO
