These graphs show the aggregated classification over three different runs, where for every category (FN, TP, TN, FP) the minimal number over the different runs is taken. For example, if 500 traces are TP in the first run, 490 in the second, and 495 in the third, then the value 490 is used as aggregated value. As a result, these graphs can show discrepancies between the classifications in different runs.
There are discrepancies. Many traces cannot be replayed on the discovered net within 10 seconds, which can also explain discrepancies. Nevertheless, there are logs for which the Inductive Miner (OR) discovered different nets over the three runs.
