We briefly introduce the rule of Mahjong and its challenges to AI algorithms. By showing the results and the application of various algorithms in the competitions, we claim that existing algorithms show promising results in Mahjong, while open problems remain and more efforts are needed towards solving this complex game.","doi":"10.24963/ijcai.2024/1020","url":"https://ijcai.org/proceedings/2024/1020","pdf":"https://ijcai.org/proceedings/2024/1020.pdf","markdown":"https://ijcai.org/proceedings/2024/1020.md","bibtex":"https://ijcai.org/proceedings/2024/bibtex/1020","volume":{"slug":"2024","title":"Proceedings of the Thirty-Third International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2024","url":"https://ijcai.org/proceedings/2024/","year":2024,"location":"Jeju, Korea","dates":"3-9 August 2024","editors":"Kate Larson","isbn":"978-1-956792-04-1","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2024"},"section":"Demo Track","track":"Demo Track","number":1020,"pages":{"first":8733,"last":8736},"keywords":["Multidisciplinary Topics and Applications: MDA: Game playing","Machine Learning: ML: Applications","Agent-based and Multi-agent Systems: MAS: Multi-agent learning","Search: S: Heuristic search","Search: S: Game playing","Machine Learning: ML: Deep reinforcement learning","Agent-based and Multi-agent Systems: MAS: Applications","Multidisciplinary Topics and Applications: MDA: Computer games"],"videos":[],"references":[{"position":1,"raw":"[Espeholt et al., 2018] Lasse Espeholt, Hubert Soyer, Remi Munos, Karen Simonyan, Vlad Mnih, Tom Ward, Yotam Doron, Vlad Firoiu, Tim Harley, Iain Dunning, et al.
