Use of genetic algorithm in optimal orbit manoeuvre

The application of genetic algorithm is discussed in the problem of minimum-fuel consumption orbit manoeuvre of spacecraft. First, the method of operation is introduced. Two examples are then given: one is soft-landing of a lunar probe from lunar satellite orbit to lunar surface; and the other is orbit manoeuvre of lunar probe from a selenocentric hyperbolic orbit to a selenocentric circular orbit. It is shown that the genetic algorithm has good convergence property and high accuracy.
