currently I am studying the "Isolation forest" algorithm proposed by
Liu, Ting and Zhou. I started reading the scikit-learn implementation
but could not find where exactly is the algorithm 2 of the original
paper implemented.

So far this is what I managed to understand: In the iforest.py file
there is the “fit” method which, if my understanding is correct,
essentially makes a call to the “_fit” method of the BaseBagging class
but there I can’t see how the algorithm 2 of the original reference is
implemented.

Any help on the details of how Itrees and Iforests are implemented is
appreciated.

If this is not the right place to ask, please let me know where is it.

Thanks for the time and help
Sergio S
