The identification of galaxy groups allows us to link the galaxies with the halos in which they resideand, in this way, link their formation and evolution with the large-scale structure of the Universe. For this reason, it is necessary to have group finders as accurate as possible. Here we present a work in progress on an algorithm that improves the performance of Friends-of-Friends identifications by including halo-based technique.
