Learning to Execute Graph Algorithms Exactly with Graph Neural Networks
Researchers have developed a method to enable Graph Neural Networks (GNNs) to precisely execute graph algorithms. Their approach involves training Multi-Layer Perceptrons (MLPs) to handle local node instructions, which are then integrated into the GNN for inference. This technique has demonstrated exact learnability for algorithms like message flooding, BFS, DFS, and Bellman-Ford under specific constraints. AI
