I wrote a program that simulates a solar system. I was able to calculate the locations for every planet on its elliptical route for any given time.
In a second project, I managed to simulate newtonian gravitational behavior (n-body problem, time-step approach).
But I'm wondering how it is possible to:
(1) find routes (different possibilities) from a given location/planet to another
(2) choose the best route according to duration or fuel consumption
So where's a good place to start?
To be more exact: It's not about writing another simulation, it's about understanding the physics behind it!
