Introducing genetic algorithms as a reliable and effective
tool to find ordered equilibrium structures, we predict minimum energy
configurations of the square shoulder system for different values of corona width 
. By varying systematically the pressure and
choosing different values of we are able to identify
complete sequences of minimum energy configurations. The results provide a deeper understanding of the system's strategies to arrange
particles in an energetically optimised fashion, leading to the competing self-assembly scenarios of cluster formation
vs. lane formation.
