2nd Global Trajectory Optimisation Competition (GTOC2)
After the success of its first edition the Global Trajectory Optimisation Competition will be held again this year and organised by the Outer Planets Mission Analysis Group of the Jet Propulsion Laboratory (JPL) as winners of last year’s competition. Read below the original text of the announcment made by JPL.
Dear Fellow Researchers,
10 October 2006
We would like to announce the "2nd Global Trajectory Optimisation Competition," organised this year by the Outer Planets Mission Analysis Group of the Jet Propulsion Laboratory (JPL). Instructions for registration are outlined below. The competition was instituted and organised last year under the leadership of Dario Izzo of the Advanced Concepts Team, European Space Agency, as a means of stimulating research in the rich area of spacecraft trajectory optimisation. As winners of last year's competition, we feel proud and honoured to act as organisers of this year's competition.
Over the last two to three decades, local optimisation methods have evolved considerably. Global optimisation methods, however, are still in their infancy. In search for the best possible trajectory, mission designers expertly perform individual local optimisations, until they find a satisfactory solution. Global optimisation techniques, while unlikely to guarantee a global optimum, can offer significant assistance in finding an acceptable solution to a given problem. Focusing on a given problem, the Global Trajectory Optimisation Competition is an excellent way to compare different global optimisation methods; offers a unique playground for researchers to test new ideas; and promotes development of methods that most efficiently explore a large and unconventional design space for optima of an unusual objective function.
Participation in the competition will be limited to the first forty researchers or researcher teams offering proposals. To register for the competition, simply contact me (Anastassios E. Petropoulos), before 03 November 2006, preferably by email (see below) including in the email a point of contact and the names and institutional affiliations of the researchers in the team. Feel free to pass on this announcement to other researchers that you think may be interested.
The competition aims to find the "best" solution to an interplanetary spacecraft trajectory optimisation problem which will be announced on 06 November 2006. Proposed Solutions must be returned within four weeks in an ASCII text format which will be specified. Solutions will firstly be verified and then ranked on the basis of the objective function which was specified for the problem.
We plan to create a website on which a list of participating teams, the problem details, and eventually the delivered solutions will be published.
A one-day workshop will be held in late January or early February 2007, where selected teams will be invited to present their methods and results. Selection of presenting teams will be based not only on the solutions but also on other criteria such as the creativity and perceived potential of the methods used. The workshop will likely be in the South-Western or Western USA, at a as yet unknown location.
Summary of important dates:
* 03 Nov 2006: Deadline to register for the competition
* 06 Nov 2006: Disclosure of competition problem
* 04 Dec 2006: Deadline for return of solutions
* Mid Dec 2006: Solutions evaluated, presenters selected
* Late Jan or early Feb 2007: One-day workshop
We look forward to receiving your registrations and your participation in the competition.
