Typical steps of an AB simulation. (a) Initially, each shape is a primitive agent (an agent is delimited by the dashed gray line). (b) When two agents interact and do not find a move that lowers the energy, they merge into a unique agent (a dimer in this case). (c) The same can happen in another point of the lattice where a better dimer can be formed. (d) Because a better dimer has been formed, the dimer formed in b is split the next time it is moved.
