````
+In order to keep results obtained with different parameters in different .json files, simply modify the corresponding parameter ("--json") passed and the values. For instance, with ```--num-executors 4``` : ```--json exact-1m-4.json```.
+Note that when changing from ML-100k to ML-1M, the parameter ```--separator ::``` should be added, and the number of users and movies should be modified.
