Table 4.

Number of iterations and time results of ExplorerChain among N sites for 30 trials of the 3 datasets. All time measurements are averaged over N sites, and the total time includes both running time and synchronization time. For ExplorerChain, the per-iteration time is computed by dividing the time by the mean number of iterations, and the additional pausing time (240 seconds per trial) between trials for result collection was deducted
