全域軌跡優化競賽 – 空間軌道設計的十年挑戰


Seminar: The Global Trajectory Optimization Competition: 10 Years of Challenge in Space Orbit Design
The Global Trajectory Competition (GTOC) was inaugurated in 2005 by the Advanced Concepts Team of the European Space Agency (ESA). The GTOC is an event taking place every one-two years over one month during which aerospace engineers and mathematicians in the world challenge themselves to solve a very difficult problem of interplanetary trajectory design. The problem is released by the winning team of the previous edition, which is usually an atypical global optimization problem over a large design space with many local optima. The objective function or constraints are unusual that no canned methods or existing software can likely fully solve the problem. This talk gives a summary of the past GTOC problems and the relevance to other mathematical problems (e.g. traveling salesman problem). Emphasis will be put on two editions: GTOC6 which a joint team of ESA/HKUST team ranked 2nd in 2012 and GTOC8 which the speaker’s team ESA/ISAS recently won the competition in September 2015.
