Detailed Description

Rosetta MGA-DSM Problem.

The problem is transcribed as an MGA-DSM problem allowing one chemical manouvre per trajectory leg. The objective function is defined as the total $\Delta V$ necessary to randezvous with the comet 67P/Churyumov-Gerasimenko.

rosetta is a box constrained single objective, continuous optimization problem of dimension 22. The problem is also part of the Global Trajectory Optimization database (GTOP)
