About this paper

Neelkamal Bhuyan, Debankur Mukherjee, Adam Wierman

ACORD coordinates agents facing changing local costs, movement penalties, and costs for disagreement with neighbors. Agents repeatedly solve local optimization problems and exchange updates with immediate neighbors, without future predictions or sharing their hitting-cost functions. Under strongly convex hitting costs and squared-ℓ₂ switching costs, its competitive ratio approaches the lower bound ½ + ½√(1 + 4/μ_min) as iterations increase.
