Description

The experimental ExplicitShooting transcription currently performs single shooting. That is, phase.states:{name} contains the initial value of the state at the start of the phase and it is propagated across each segment continuously.

dymos should also support multiple shooting, where phase.states:{name} contains the state value at the start of each segment, and each segment is propagated independently. Constraints on discontinuities between state values at the segment boundaries should be provided to the optimizer. The first state value in each segment should be a design variable (except for the first segment in the case of fix_initial=True).
