As another mainstream navigation method based on structured memory, topological navigation is based on the principle of topology, which uses the connection relationship between nodes and edges to describe the environment and construct a topological map.
Based on the three-dimensional potential flow theory, the multi-domain method is improved from three levels: internal domain, external domain and wave excitation, and different levels of numerical calculation models of ship hydrodynamics are put forward, forming a set of systematic, accurate, stable, efficient and widely applicable methods for studying and analyzing ship motion and its application, which has important research and engineering practical value.
