Decentralized Model Predictive Control of Connected and Automated Vehicles with Coupled Safety Constraints

What the math gives to ML

The paper offers a constructive way to handle coupled, nonconvex pairwise safety constraints in a decentralized controller: replace each pairwise collision constraint by a locally enforceable half-space derived from a buffered Voronoi partition around announced neighbor trajectories. Its second transferable mechanism is iterative non-cooperative coordination, with Jacobi updates using stale peer plans and Gauss-Seidel updates using the newest available plans. A strong neural-network transfer is a safety-filtered decentralized multi-agent policy or world model in which each agent proposes an action, then projects it onto buffered Voronoi constraints induced by peer predictions. The key falsifiable signature is that sufficiently large safety buffers eliminate violations while the decentralized fixed-point iteration becomes stable only when the effective cross-agent coupling has spectral radius below one.
