About Me

I am currently an MSc student at the National University of Singapore (NUS), College of Design and Engineering. I conduct research in the Multi-Agent Robotic Motion (MARMot) Laboratory, advised by Asst. Prof. Guillaume Sartoretti.

Prior to joining NUS, I obtained my B.Eng in Aircraft Control and Information Engineering from the University of Electronic Science and Technology of China (UESTC), where I ranked 4/22 and was exempted from the National Postgraduate Entrance Examination due to academic excellence.

Currently, I am also delving into the field of Embodied AI. I firmly believe that this research direction has the potential to change the world.

My research interests lie at the intersection of Multi-Agent Systems, Reinforcement Learning, Robotic Control, Combinatorial Optimization, and Path Planning. Specifically, I focus on:

  • Data-driven and learning-based control
  • Distributed multi-agent systems
  • Event-triggered control
  • Multi-objective Optimization for MAS decision-making

Selected Publications

CAMO Paper Cover

CAMO: A Conditional Neural Solver for the Multi-objective Multiple Traveling Salesman Problem

Fengxiaoxiao Li*, Xiao Mao*, Mingfeng Fan, Yifeng Zhang, Yi Li, et al.

Submitted to IEEE/RSJ International Conference on INTELLIGENT ROBOTS SYSTEMS (IROS), 2026.

Proposed a DRL-based framework CAMO for MOMTSP, achieving zero-shot generalization to various problem scales via conditional attention mechanisms and a decoupled collaborative decoder. Replaced the traditional hours-long inference time with seconds-level real-time reasoning while outperforming heuristic baselines (NSGA-III/MOEA/D) and DRL baselines (MO-PARCO).

Research Experience

Learning-Driven Optimization for MOMTSP and MOHCVRP

Research Assistant | NUS MARMot Lab | Jan 2026 - Present

Advisor: Asst. Prof. Guillaume Sartoretti

  • Developed a Transformer-based Autoregressive Model to generate diverse Pareto-optimal solution sets for multi-objective routing.
  • Implemented multi-agent RL with sparse rewards and transformer-based inter-agent communication.
  • Evaluated against heuristic baselines (e.g., NSGA-III/MOEA/D) and DRL baselines (e.g., DRL-MOA, PMOCO, MO-PARCO), demonstrating strong hypervolume performance and rapid inference speed to prove the high efficiency of our method.

Multi-Objective Optimization for Multi-Robot Systems based on Deep Reinforcement Learning (CAMO)

Research Assistant | NUS MARMot Lab | Aug 2025 - Mar 2026

Advisor: Asst. Prof. Guillaume Sartoretti

CAMO Project IROS Paper Figure
  • Project Overview: Addressed the MOMTSP generalization challenge by proposing a DRL-based framework, CAMO, achieving Zero-shot Generalization to various problem scales via conditional attention mechanisms.
  • Architecture Design: Proposed a Conditional Encoder to efficiently fuse multi-objective preferences and instance information, replacing residual connections with gated aggregation. Pioneered a decoupled Agent/Node-selection collaborative decoder to break input dimension constraints and bestow dual scalability.
  • Performance Breakthrough: Improved the REINFORCE algorithm and dynamic sampling strategy. Outperformed heuristic baselines (NSGA-III/MOEA/D) and DRL baselines (MO-PARCO), reducing inference time from hours to seconds. Validated practical deployment viability on a ROS-based mobile robot platform.
