Benchmarking Robustness and Generalization in Multi-Agent Systems: A Case Study on Neural MMO

We present the results of the second Neural MMO challenge, hosted at IJCAI 2022, which received 1600+ submissions. This competition targets robustness and generalization in multi-agent systems: participants train teams of agents to complete a multi-task objective against opponents not seen during training. We summarize the competition design...

Designing a Title Certificate for the Chinese 3D Cadastre

When the land use pattern changes from an extensive way to an intensive way, the development of 3D land-use has become reality. Due to the vertical heterogeneity of property rights, establishment of 3D cadastre is imperative. Meanwhile, registration and certification of the property rights have become important approaches to serve public and...
