In Proceedings of the 20th International Conference on Autonomous Agents and MultiAgent Systems (AAMAS '21). Cooperation and Reputation Dynamics with Reinforcement Learning. Nicolas Anastassacos, Julian García, Stephen Hailes, and Mirco Musolesi.We conclude that mitigating this coordination challenge can improve scalability more than the choice of learning type. Our results show that the task's unique social features, in particular the challenge of agents' physical coordination, causes both centralised and decentralised approaches to scale poorly. A mathematical model based on the replicator dynamics allows us to further study how the task's social dynamics affect the emergent behaviour. Using neuroevolution, we empirically investigate scalability comparing centralised and decentralised approaches. We introduce a new task for studying cooperation: agents can solve the task by working together and specialising in different sub-tasks, or by working alone. Understanding this trade-off is important, but systematic comparisons have been limited to tasks with fully aligned incentives. A centralised solution bypasses these challenges, but may scale poorly with system size. Decentralised learning of cooperation is difficult because interactions between agents make the environment non-stationary, and the reward structure tempts agents to act selfishly.

Students will complete the game with an understanding that food supply chains are complex, learning that decisions at each stage can influence the nutritional quality, waste generated and economic viability of the product.Įmail: FAQ How can I download the Farm to Fork game?įarm to Fork is available now as a free download from the App Store. The game centres on the journey of a food commodity – the humble potato – from production to consumption (farm to fork), with levels and challenges to highlight learning outcomes at each stage. The game was developed by academics across ECU’s Schools of Medical and Health Sciences, Science, Education, and Arts and Humanities, in collaboration with school students and teachers. Newly released to the App Store, Farm to Fork has been designed to provide teachers and home schooling parents with an interactive and immersive tool with which to educate students about the health, economic, scientific and social realities of food production systems. Now, a group of ECU researchers has developed a timely new educational video game aimed at helping adolescents make sense of how food production and the supply chain works.įarm to Fork is a brand-new transformational video game aimed at students from Years 6 through 9, specifically developed as a free resource for educators in line with the school curriculum. Many consumers, including young people, interpreted empty shelves and limitations on staples like flour, pasta and rice with alarm, believing them to indicate genuine shortages of foods and other products as opposed to disruptions to the supply chain. This year has seen Australians confronted by bare supermarket shelves and major restrictions on their grocery purchases for the first time in their lifetimes, as a result of the COVID-19 pandemic.
