Feature weight by Relief

cts____

Hi, I am a beginner at RapidMiner and unfamiliar with it.

I saw that RapidMiner offers feature selection by the node "Feature Weight by Relief". However, I would like to know which Relief algorithm does the node implement, as there are a few such as Relief, ReliefF and RReliefF.

The node requires the parameters k_nearest_neighbor so it can't be Relief, so might it be that it is ReliefF?

If anyone knows the algorithm used, please let me know, and please attach any links to documentation that states what algorithm is used if there is any
