This edition was organised by Ya-zhong Luo and Hong-Xin Shen from College of Aerospace Science and Engineering, National University of Defense Technology and State Key Laboratory of Astronautic Dynamics, Xi’an Satellite Control Center. The official competition web site can be found here.
In a nutshell
Twelve stations placed in a to-be-found Dyson ring were tasked to build the mega-structure. Ten spacecraft starting from the Earth had to tour the asteroid belt to activate as many asteroids as possible using a minimal propellant consumption. Each activated asteroid had to complete a low-thrust, constant acceleration spiral aimed at reaching a chosen target station repleneshing its building material.

Curiosities
The competition ended on the 7th of November, which also was the same day in which the problem was released back in 2005 for the first edition of the GTOC series. In that first edition a team from Tsinghua University, School of Aerospace Engineering, who won this edition, participated ranking last.
NOTE:
Most teams published a paper in the journal Journal Acta Astronautica detailing the results of the competition.
