Identify the candidate nodes using only the minimum number of revisions to keep

Problem/Motivation

We will identify the candidate nodes in 3 steps (each step will use one more variable until we use it the 3) this will allow us to have at least the deletion feature in the module and will allow the release of the beta 1. In the next beta version, we will add the other 2 variables in the next releases.

Proposed resolution

Use the minimum number of revisions to keep variable to identify the candidate nodes.
