In a nutshell
An asteroid sample return mission had to be designed to 3 out of 140 asteroids. Earth fly-bys were allowed. The objective function was the ratio between the final spacecraft mass and the total mission time plus a term rewarding longer stay times on the asteroids to increase the science return.

Led by Regís Bertrand, the team from Centre National d’Etudes Spatiales (CNES) won this edition with a trajectory employing four Earth fly-bys.
The first four best trajectories selected the same asteroid sequence and differed only by the location and number of extra Earth fly-bys.
The final objective function values of the best trajectories were extremely close.
