1. IntroductionIn recent years, game theory has been adopted in various application fields, such as control of unmanned systems [1], multi-agent exploration policies [2], collective decision making [3], communication networks [4], and cooperative advertising strategy [5]. As an important part of game theory, the Nash equilibrium (NE)-seeking problem within multi-agent systems (MASs) has attracted increasing interest among scholars in multi-agent communities [6,7,8,9,10,11,12].

Abstract:Spatial relation models are the basis for realising three-dimensional spatial analysis. More researchers are now focusing on models that combine topological relations with distance or directional relations; however, a model that unifies all three relations has not yet been developed. In particular, it is more effective to use different spatial relations between features with different spatial characteristics in three-dimensional electronic navigation charts (3D ENC).
