To mathematically prove the packing optimality of golden angle phyllotaxis using convex optimization and spectral bounds under radial growth constraints.
Applied convex optimization and semidefinite programming (SDP) hierarchies to determine rigorous limits for two-dimensional circle packing.
Modeled divergence angles using the golden ratio (φ ≈ 1.618) and irrational rotations to examine five-fold quasicrystalline symmetry in plant growth patterns.
Confirmed that the golden angle (137.5077°) provides the optimal packing solution under radial growth constraints.
Verified theoretical packing density limits approaching π/(2√3) ≈ 0.9069 using spectral bounds derived from semidefinite programming.
