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,
DIDO (nuclear reactor) for use in neutron diffraction. DIDO was shut down in 1990. The primary facilities decommissioning is expected to be complete in 2023 with the reactor decommissioning completed in 2031 and final site clearance achieved in 2064 In all, six DIDO class reactors were constructed based on this design: HIFAR was the last to shut down, in 2007. DIDO (nuclear reactor) DIDO was a materials testing nuclear reactor at the Atomic Energy Research Establishment at Harwell, Oxfordshire in the United Kingdom. It used enriched uranium metal fuel, and heavy water as both neutron moderator and primary coolant. There was also a
