Vasile, Massimiliano Combining evolution programs and gradient methods for WSB transfer optimisation. (English) Zbl 1051.90536 Ciriani, Tito A. (ed.) et al., Operations research in space and air. Dordrecht: Kluwer Academic Publishers (ISBN 1-4020-1218-7/hbk). Appl. Optim. 79, 85-102 (2003). Summary: Weak Stability Boundary transfers are optimised using a combination of two different optimisation techniques: Evolution Programs and Nonlinear Programming. The former is an heuristic approach to the problem derived from the Genetic Algorithms while the latter is a gradient method. In order to make Evolution Programs more efficient in solving general problems with a floating point data structure (like orbit design problems) a special set of genetic operators have been introduced to improve convergence and robustness. The benefit of the new operators and of the combination of the two methods have been proved solving a difficult orbit design problem. Some examples of optimised orbit will be presented.For the entire collection see [Zbl 1013.00013].
