If a spaceship was launched from earth with the goal to go as fast as possible (so it can go as far as possible as quickly as possible). What speed can it achieve? How many assists should (or can) it use?
The solution will show the paths of greatest velocity, along with the velocities the ship can obtain.

This project acts as my midterm and final exam for PHYS 3150 - Computational Physics - at Clemson University.
The star data was retrieved from hyg.
- The only objects in the universe are fixed stars (with velocities).
- The ship is the proposed second stage of the SLS
- The engine is an ideal rocket-propulsion engine
- Mass-luminocity equation
- (L/L0) = (M/M0)^a, a = 3.5
- Tsiolkovsky rocket equation
- vf = v0 + ve*ln(M0/Mf)
- Gravitational Assist
- (1-m/M)(vi+2u)sqrt(1-((4uvf(1-cos(theta)))/(vi+2u)^2))
- The program currently only considers one set of values
- Recursion depth is hard-coded
- Sorting is used too much/takes too long
- Only considers one octant of universe
- Does not record time
- Paths due not prune as much as they should
- Only stars are plotted, not vectors
- Contains dead code
