  We present a numerical algorithm to evaluate the self-consistent field theory
for melts composed of block copolymers with multiply-branched architecture. We
present results for the case of branched copolymers with doubly-functional
groups for multiple branching generations. We discuss the stability of the
cubic phase of spherical micelles, the A15 phase, as a consequence of tendency
of the AB interfaces to conform to the polyhedral environment of the Voronoi
cell of the micelle lattice.
