An answer is one of these classifications supported by finite-size analysis that controls the $L \\to \\infty$ limit, or by a proof.","problem_ref":null,"references":"","settled_by":"Equilibrium simulations or ground-state computations at sizes large enough to fix the L dependence of P(q) and of domain-wall and sponge excitation energies without ambiguity.","status_note":"Simulations at accessible sizes look RSB-like, while droplet proponents argue these sizes are preasymptotic (M.
