Abstract (in Japanese) (See Japanese page) 
(in English) Deciding efficient and safe courses of ships before actual navigation is very important. We have developed multi-agent reinforcement learning system (MARLS) to search ships’ courses as a useful tool to discuss the appropriateness of courses and the interaction between maneuvering actions. Recently, we have considered the introduction of reference courses to MARLS to increase the value of MARLS as the tool. In this research, we propose a more simple method to trace the reference courses than Ref. [12] and evaluate the influence of updating reference courses on MARLS through the numerical simulations.
