I have a question: for the challenge #2-predict, is it acceptable if
our team submit more than one prediction file? If yes, what is the
maximum number of the files? Your clarification on this is appreciated.

with reasonable limits.
For instance, if you can choose between different parameter

approach is using social networks between developers and another is
using complexity metrics, I welcome you to submit both (or all of
To give you a number, I think three prediction files for each category
(changes, bugs) is reasonable.
