LABS on a GH200: Exponent 1.24 to the Proven Optimum, Beside the QAOA Exponents
GPU Memetic Tabu With 4,096 Islands vs lMAts; Exact Branch-and-Bound Matches All 46 Published Optima.
1.240GPU wall-TTS base b, N = 40–66
46/46exact optima equal the P&M table
3 of 6N > 66 best-knowns reached (lMAts 0)
4,096islands on one GPU
- GPU wall TTS ∝ 1.240N (N 40–66) vs lMAts 1.352N
- Exact B&B: 46/46 optima equal the published table
- N = 67, 71, 75: GPU reaches the best-known value; lMAts at none
