E = \sum_{ij} J_{ij} S_i S_j Actually, I was wrong cause we can really put whatever we want in J_{ij}, is that right ? If we do so, we can also approximate the solution that minimizes the energy function ?

Hello, First of all, sorry if my question is trivial but I'm not a physicist ;-) I heard a lot about the Ising model used to compute the energy of a system with 2 states. This model seems to be a bit "simple" because it assumes that particles interact with their nearest neighbors only. I was...
