DSAI Team Wins First Place in AgentX International Competition

A team from the Department of Data Science and Artificial Intelligence (DSAI) (comprising Ph.D. student Mr HUANG Beichen, Prof. CHENG Ran, and Prof. TAN Kay Chen) has achieved a remarkable milestone by winning first place globally in the Multi-Agent Systems track of the prestigious AgentX International Competition. The event, hosted by the University of California, Berkeley, and supported by leading technology companies such as Google, Amazon, and Hugging Face, is one of the most prominent global platforms for advancing Large Language Model (LLM) agent technologies.   Overview of the the AgentX - LLM Agents MOOC Competition (Spring 2025)   The competition attracted nearly 1,000 teams from over 100 countries and 800 universities worldwide, including institutions such as UC Berkeley, Stanford, and CMU. After multiple rounds of rigorous evaluation by a judging panel composed of 28 experts from Google DeepMind, Meta FAIR, Nvidia, and other top-tier organizations, only 15 teams advanced to the final on-site Demo Day. The DSAI team was the only representative from China and emerged as the First Place in the most technically demanding category with their pioneering project, EvoGit.   EvoGit constructs the evolutionary process of code as a Directed Acyclic Graph (DAG), on which multiple agents collaboratively evolve and continuously develop.   EvoGit is a decentralized multi-agent framework that reimagines software development as a continuously evolving process rather than a static task. It models the development lifecycle as a directed acyclic graph (DAG) of Git commits, where multiple agents independently propose small code changes or structural crossovers and collaborate without relying on central schedulers or explicit communication protocols. This architecture enables self-organizing agent behavior, leading to a scalable and resilient development process. Built on standard Git infrastructure, EvoGit also supports seamless human-agent collaboration, allowing developers to inspect, intervene, and interact with the system using familiar version control tools.     📣For more information, please visit: 🧬 EvoGit Paper (arXiv) 💻 EvoGit Open Source Repository

DSAI Team Wins the Best Paper Award at IEEE CEC 2025

At the 2025 IEEE Congress on Evolutionary Computation (IEEE CEC 2025) recently held in Hangzhou, China, the team from DSAI received the prestigious Best Paper Award. The IEEE CEC is a prominent international conference in the field of evolutionary computation, providing a platform for researchers and practitioners worldwide to share research findings and exchange academic ideas. As one of the three flagship conferences of the IEEE Computational Intelligence Society (IEEE CIS), IEEE CEC began in 1994, initially held as the "IEEE Symposium on Evolutionary Computation" in Orlando, Florida, USA. Over the years, IEEE CEC has grown into a significant event in the evolutionary computation community, attracting scholars from around the globe to explore cutting-edge topics and inspire academic exchanges. Notably, this year's IEEE CEC was hosted independently in China for the first time, drawing participants from 145 countries and regions worldwide. The conference delivered a vibrant and engaging academic feast for all attendees. The award-winning paper, titled “A Theoretical Analysis of Evolutionary Transfer Optimization”, was co-authored by DSAI postdoctoral fellows Dr XUE Xiaoming, Dr FENG Yinglan, Dr LIU Rui, and DSAI Head and Chair Professor of Computational Intelligence Prof. TAN Kay Chen, along with Prof. FENG Liang from Chongqing University and Prof. ZHANG Kai from Qingdao University of Technology. This study first links the three core subprocesses of analogical reasoning (“retrieval”, “mapping”, and “evaluation”) to the three key issues in knowledge transfer (“what to transfer”, “how to transfer”, and “when to transfer”). Subsequently, focusing on the concept of “similarity” in analogical reasoning, the research establishes theoretical foundations for knowledge transfer methods addressing the three key issues. By constructing composite functions, it systematically analyzes the greatest lower bounds of performance gains in analogy-driven transfer methods, thereby theoretically revealing both the potential and limitations of knowledge transfer. Finally, from the perspective of the “no free lunch theorem”, the study reveals the fundamental distinction between evolutionary transfer optimization (ETO) and traditional evolutionary optimization (EO). ETO introduces a novel perspective for embedding search biases, leveraging task relationship-based knowledge transfer operations that are designed to surpass traditional evolutionary operations, thereby enhancing the performance of EO. This research offers a rigorous theoretical basis for analogy-based ETO and provides a macro-level lens to evaluate the capabilities and boundaries of knowledge transfer strategies. Looking ahead, the team will continue to focus on the theoretical exploration and algorithm design of knowledge transfer in the field of optimization. Their goal is to develop intelligent optimization systems capable of autonomously inheriting and applying experience, effectively addressing diverse optimization challenges arising from problem scale expansion, environmental changes, or shifting demands.   Official website of IEEE CEC 2025: https://www.cec2025.org/ Link to the paper: https://arxiv.org/abs/2503.21156
