Dido the time of Dido. Even with the date of 864 BC that historical revisionist David Rohl gives for the end of the Trojan War, Aeneas would have been about 77 years old when Dido fled Tyre in 825 BC and 88 when she began to build Carthage in 814 (following Peñuela's reconstruction), hardly consistent with the romantic intrigues between Dido and Aeneas imagined by Virgil in the "Aeneid". Virgil's references in the "Aeneid" generally agree with what Justin's epitome of Trogus recorded. Virgil names Belus as Dido's father, this Belus sometimes being called Belus II by later commentators to distinguish
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
