> However, if we wanted to rigorously benchmark AlphaChip against simulated annealing or other floorplanning algorithms, we have to afford the same compute and runtime budget to each algorithm.
The Nature authors already presented such a study in their appendix:
"To make comparisons fair, we ran 80 SA experiments sweeping different hyperparameters, including maximum temperature (10^−5, 3 × 10^−5, 5 × 10^−5, 7 × 10^-5, 10^−4, 2 × 10^−4, 5 × 10^−4, 10^−3), maximum SA episode length (5 × 10^4, 10^5) and seed (five different random seeds), and report the best results in terms of proxy wirelength and congestion costs in Extended Data Table 6"
