Serial staging with single rocket engine design (cont)

Design starts from the last segment of the flight trip going backwards to the surface of the earth.
For the sequence from GEO to the final position, no staging was used, but a single rocket engine RL10B-2 (Isp=462) with calculated sufficient fuel used.
Going backwards, for trip n, optimal mp and ms was found. mp+ms was then added to the payload for the purpose of finding the ms and mp of trip n-1.
For the trip from LEO to GEO, the optimization algorithm was applied to try for 1,2, or 3 stages with the selected engines from before.
