A bigger, cleaner, faster version of DIVA

DIVA is an Adams integrator written by Krogh for use at NASA's Jet Propulsion Laboratory in Pasadena. When written, DIVA was more efficient than other integrators on the applications at JPL and this remains the case 30 years later. But all good things come to pass and it now necessary to re-write and extend DIVA.

I will give a brief history of DIVA, discuss the reasons why it must be re-written and extended, and highlight the distinctive features the integrator will have. Little knowledge of linear multistep methods will be required to understand the seminar.
