Guidance Graph Optimization for Lifelong Multi-Agent Path Finding

IJCAI 2024poster

We study how to use guidance to improve the throughput of lifelong Multi-Agent Path Finding (MAPF). Previous studies have demonstrated that, while incorporating guidance, such as highways, can accelerate MAPF algorithms, this often results in a trade-off with solution quality. In addition, how to ge…

Arbitrarily Scalable Environment Generators via Neural Cellular Automata

NeurIPS 2023poster

We study the problem of generating arbitrarily large environments to improve the throughput of multi-robot systems. Prior work proposes Quality Diversity (QD) algorithms as an effective method for optimizing the environments of automated warehouses. However, these approaches optimize only relatively…

Multi-Robot Coordination and Layout Design for Automated Warehousing

IJCAI 2023poster

With the rapid progress in Multi-Agent Path Finding (MAPF), researchers have studied how MAPF algorithms can be deployed to coordinate hundreds of robots in large automated warehouses. While most works try to improve the throughput of such warehouses by developing better MAPF algorithms, we focus on…

Surrogate Assisted Generation of Human-Robot Interaction Scenarios

CoRL 2023oral

As human-robot interaction (HRI) systems advance, so does the difficulty of evaluating and understanding the strengths and limitations of these systems in different environments and with different users. To this end, previous methods have algorithmically generated diverse scenarios that reveal syste…

Deep Surrogate Assisted Generation of Environments

NeurIPS 2022accept

Recent progress in reinforcement learning (RL) has started producing generally capable agents that can solve a distribution of complex environments. These agents are typically tested on fixed, human-authored environments. On the other hand, quality diversity (QD) optimization has been proven to be a…
