Graph neural network solves multicut problem faster than heuristics

Researchers have developed a novel graph neural network architecture specifically tailored for the multicut problem, an NP-hard optimization challenge. This new method assigns features to edges and computes messages based on graph triangles, outperforming existing heuristic solvers in solution quality and runtime. Experiments on instances up to 200 nodes demonstrated that the approach can find optimal solutions in seconds, a task that typically takes hours for exact solvers. AI
