About the Project

OPtiMaL (Online Procedural Content Generation via Multi-objective Optimisation and Learning) aims to introduce generative AI algorithms that are capable of creating multimodal content with multi-dimensional diversity, which is aware of human behaviour and adapts to human experience. OPtiMaL adopts a new multi-objective optimisation and learning approach to procedural content generation, which is generally applicable across many domains.

The approaches developed in OPtiMaL will be validated initially on digital games with direct applications to domains that involve the simulation of human behaviour including construction, manufacturing, education, and autonomous driving. OPtiMaL is a collaborative project between one of the leading centres of Al in games research worldwide - Institute of Digital Games, Malta - and one of the world's leading research groups in computational intelligence - SUSTech, China.

One of the long-term goals of the project is to position Malta centrally on the global Al research map and place China as a global leader in Al in digital games.


The project is spearheaded by the Institute of Digital Games, Malta and SUSTech, China.

Project OPtiMaL received funding from the Malta Council for Science and Technology (MCST) and the Ministry for Science and Technology of the People’s Republic of China (MOST), through the SINO-MALTA Fund 2022 (Science and Technology Cooperation).


13-04-2024 | Workshop on Computational Intelligence and Games

The recent workshop on Computational Intelligence and Games, held on April 13, 2024, at Southern University of Science and Technology (SUSTech) in Shenzhen, was a resounding success. Organised by one of OPtiMaL's coordinators, Jialin Liu the workshop brought together over 50 participants, including leading researchers, students, and industry professionals in the field of AI and games.

It was an honor to host H.E. John Busuttil, Ambassador of Malta to China, who delivered an insightful address that added depth to the discussions and highlighted the importance of the ongoing collaboration in AI research. The workshop was filled with engaging sessions and keynote presentations from experts such as Georgios N. Yannakakis, Jichen Zhu, Mike Preuss, and others. The involvement of Tencent, one of the largest gaming companies, brought an industry perspective to the event, further enriching the discourse on AI and gaming.

Held at the College of Engineering Building at SUSTech, China, the OptiMal funded workshop was supported by several prestigious organizations, including the Department of Computer Science and Engineering (CSE) and the Research Institute of Trustworthy Autonomous System (RITAS), with backing from the IEEE Computational Intelligent Society (CIS). Attendees had the opportunity to network, discuss recent advancements, and explore future directions in AI and games. For more information about the workshop, visit https://aingames.cn/CIG2024/.

17-01-2024 | Professor Georgios Yannakakis Takes OptiMaL to South America

Professor Yannakakis's recent visit to South America served as a dual opportunity – not only did it allow him to share the exciting developments of the OPtiMaL Project, but it also fostered collaboration and knowledge exchange with experts in the region. A significant highlight of his journey was his invited talk at "Congreso Futuro" the largest popular science conference in Latin America. This prestigious event annually convenes visionaries, scientists, and thought leaders to delve into the future of science, technology, and innovation. Serving as a unique platform, Congreso Futuro enables the dissemination of groundbreaking research and ideas to a diverse and engaged audience. During his captivating presentation, Professor Yannakakis unveiled the aims and achievements of the OPtiMaL Project, alongside other insightful topics, offering a glimpse into the forefront of AI innovation.
