Dido that Iarbas had specifically requested Dido as wife. Dido was trapped by her words. Still, she preferred to stay faithful to her first husband and after creating a ceremonial funeral pyre and sacrificing many victims to his spirit in pretense that this was a final honoring of her first husband in preparation for marriage to Iarbas, Dido ascended the pyre, announced that she would go to her husband as they desired, and then slew herself with her sword. After this self-sacrifice Dido was deified and was worshipped as long as Carthage endured. In this account, the foundation of Carthage occurred
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
