Cover Story: This paper proposes a novel trajectory optimization method using function trees encoded as genetic programs to produce three-dimensional geographic flight routes. Genetic programming (GP), a form of evolutionary computation and an artificial intelligence technique, is used to optimize these functions over tens or hundreds of generations (iterations). A heuristically optimal route is found by applying selective pressures to a population of genetic programs, such as non-intersection with obstacles and restricted areas, along with minimized distance and travel times. GP parameterization is also explored, and its advantageous and detrimental effects are discussed. The proposed algorithm outperforms existing methods in terms of speed and robustness, highlighting the potential for GP applications to complex spatial optimization problems. View this paper
