- Method Detail
  - generateUserLists
```
private void generateUserLists(int[] UsersDistribution)
```
    Creates lists of incremental userIds, based on the given distribution of users per user type
    Parameters:
    UsersDistribution -
    an array with 4 integers defining the number of users per rating type.
    
    Specifically:
    
    - UsersDistribution[0] = Number of malicious users
    
    - UsersDistribution[1] = Number of strict users
