Hi Sergio,
In IsolationForest, BaseBagging is applied with ExtraTreeRegressor as
base_estimator. Algorithm 2 (iTree) of the original paper is thus

The forest is implemented thanks to the bagging procedure.

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
ther
