QUACOD: Quantum Optimization via Coordinate Descent for Scalable Drone Scheduling

Hoang-Quan Nguyen, Ilya Safro, Khoa Luu, Samee U. Khan, Van-Quang-Huy Nguyen

QUACOD decomposes drone scheduling into quantum-solvable subproblems to scale five times larger than direct methods on limited qubits.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

In our experiments, QUACOD outperforms the state-of-the-art (SOTA) quantum-based drone scheduling method not only in optimized drone completion times but also in scalability, handling up to 5 times more drones and 35 times more routes.

C2weakest assumption

That decomposing the original high-complexity drone scheduling problem via coordinate descent into subproblems solved independently on quantum hardware yields solutions that are competitive with or better than solving the full problem directly.

C3one line summary

QUACOD decomposes drone scheduling into quantum-solvable subproblems via coordinate descent, outperforming prior quantum methods in completion time while scaling to 5x more drones and 35x more routes.
