RF were compared with GBR methodology. As previously discussed, learners of the GBR was kept weak intentionally to refrain the greedy growth of the methodology. The imposed constraints kept the learner leaves less (or equal) than 3, and the learners depth less (or equal) than 5. Therefore, in both lines of OF, an increase of the distances were observed. However, it should be mentioned that the current strategy to consider the aforementioned constraints, limited the range of reported distances, in which the average and maximum distance in the two OFs approached to each other.
