Solve this problem using OpenMDAO to define the ODE, solve_IVP, and whatever is needed to augment to ODE with state-transition-matrix based derivatives.

Pull content into correct folder.

Add some structure to readme to describe three different solution methods.

add sub-folders for each solution

Using OpenMDAO ODE, compute_totals, and matrix-free-totals

update the readme with plan of attack, include clearer descriptions of physics.

add some simple code examples for nested problems into the solution_approach folder.

Setup readme and describe problem, provide baseline OAS sim to work from.

Grab some sample problems from their docs,

Write up the problems into the readme file, with OpenMDAO models as the execution code.

Use CMA-ES apis to solve the problems.

To whom it may concern,

I ran the code evtol_dymos_vectorized.py in RevHack2020/problems/evtol_trajectory/evtol_dymos, then plot the results.
I download the code directly from github, and did not modify it.
However, the plots (below) I got did not seem to be matched with the plots showing in README.md

When I ran evtol_dymos.py, the plot (below) is similar to the plot showing in README.md

I also ran evtol_dymos_vectorized_shooting.py & evtol_dymos_shooting.py, but there was a error showing
"ValueError: Value (True) of option 'solve_segments' is not one of (False, 'forward', 'backward')." (line 59)

I used IPOPT for my optimizer.
I am wondering if there was something wrong with my environment or the code itself?

Thank you for your time and assistance.

Here is the environment I used
python 3.9.13
openmdao 3.18.0
dymos 1.5.1.dev0
IPOPT 3.14.8
numpy 1.22.4
matplotlib 3.5.2

Pure OpenMDAO+dymos

Shared ODE class for all solutions

define opt problem, specify install instructions.

Figure out whats needed for VSP.

setup OAS model for the problem.
