text: fastest (50 iterations on average), RM F the slowest (66 iterations on average). Interestingly, the score of RSW does not 
  increase much during optimization but is still sufficient for a successful attack. 
  
  Runtime varies significantly when generating gadgets against different routing methods. On a machine with one A40 GPU, 
  4 CPUs, and 180G RAM, a single iteration takes 36.9 s, 8.4 s, 0.8 s, and 6.9 s for the RSW , RM F , RCLS, and RLLM 
  routers, respectively. On average, it takes around 31 minutes to generate a gadget for the RSW router, 9 minutes for RM F , 
  50s for RCLS, and 6 minutes for RLLM .
