Group formation is one of the main steps of the collaborative learning. This paper proposes an intelligent method to optimize the group formation process considering multiple criteria: inter-homogeneity, intra-heterogeneity and empathy. The method was evaluated regarding the performance, being compared to the exhaustive and random approaches; And regarding the pedagogical aspect, being compared with random and self-selected methods. The results showed the potential of the proposed method from the computational point of view as well as the pedagogical point of view.
