DIDO (software) used to solve problems in aerospace, robotics and search theory. The optimal control toolbox is named after Dido, the legendary founder and first queen of Carthage who is famous in mathematics for her remarkable solution to a constrained optimal control problem even before the invention of calculus. Invented by Ross, DIDO was first produced in 2001. The software is widely cited and has many firsts to its credit: Several different versions of DIDO are available from Elissar Global. DIDO (software) DIDO ( ) is a software product for solving general-purpose optimal control problems. It is widely used in academia, industry,
HMS Dido (1896) HMS Dido (1896) HMS "Dido" was an protected cruiser built for the Royal Navy in the mid-1890s. Eclipse-class second-class protected cruisers were preceded by the shorter Astraea-class cruisers. "Dido" had a displacement of when at normal load. It had a total length of , a beam of , a metacentric height of around , and a draught of . It was powered by two inverted triple-expansion steam engines which used steam from eight cylindrical boilers. Using normal draught, the boilers were intended to provide the engines with enough steam to generate and to reach a speed of ; using forced
