JPL Announces 2nd Global Trajectory Optimisation Competition (GTOC2)
10 October 2006 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), winners of last competition.
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.

Dear Fellow Researchers,
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:
