TwinLoop: Simulation-in-the-Loop Digital Twins for Online Multi-Agent Reinforcement Learning
Decentralised online learning enables runtime adap-tation in cyber-physical multi-agent systems, but when operatingconditions change, learned policies often require substantial trial-and-error interaction before recovering performance. To addressthis, we propose TwinLoop, a simulation-in-the-loop digital twinframework for online multi-agent reinforcement learning. Whena context shift occurs, the digital twin is triggered to reconstructthe current system state, initialise from the latest agent policies,and perform accelerated policy improvement with simulationwhat-if analysis before synchronising updated parameters backto the agents in the physical system. We evaluate TwinLoop in avehicular edge computing task-offloading scenario with changingworkload and infrastructure conditions. The results suggest thatdigital twins can improve post-shift adaptation efficiency andreduce reliance on costly online trial-and-error.

Case Study: Vehicular Edge Computing Task Offloading
TwinLoop was evaluated in a VEC scenario where vehicles offload computation-intensive tasks to nearby Road-Side Units (RSUs). This dynamic environment, characterized by changing network conditions, vehicle mobility, and fluctuating task demand, served as a representative testbed. TwinLoop demonstrated significant improvements in adaptation efficiency and a reduction in reliance on costly online trial-and-error interactions after environmental shifts, such as increased vehicle density or server degradation.
Key Takeaway: TwinLoop provides a robust framework for managing dynamic task offloading decisions in complex, real-world VEC environments.
