  We propose an optimisation method for the inverse structural design of
self-assembly of anisotropic patchy particles. The anisotropic interaction can
be expressed by the spherical harmonics of the surface pattern on a patchy
particle, and thus arbitrary symmetry of the patch can be treated. The pairwise
interaction potential includes several to-be-optimised parameters, which are
the coefficient of each term in the spherical harmonics. We use the
optimisation method based on the relative entropy approach and generate
structures by Brownian Dynamics simulations. Our method successfully estimates
the parameters in the potential for the target structures, such as square
lattice, kagome lattice, and dodecagonal quasicrystal.
