Researchers have developed GREAT, a novel Graph Edge Attention Network designed to tackle complex electric vehicle routing problems with asymmetric costs. Unlike previous methods that rely on node coordinates, GREAT operates in edge space, making it more suitable for non-Euclidean metrics like energy consumption. Integrated into a reinforcement learning framework, GREAT optimizes both routing and charging decisions, outperforming existing heuristics in energy reduction and runtime efficiency. The model also demonstrates state-of-the-art performance on standard routing problems like the Traveling Salesman Problem and Capacitated Vehicle Routing Problem when adapted for non-Euclidean settings.
