The Newton-polytope determination conjecture for points on hypersurfaces

From papers

Let CfC_f be the hypersurface defined by a polynomial ff, let HfH_f be its Newton polytope, let G(H)G(H) be the greatest common divisor of all coordinates of all elements of HH, and let cmathcalE(Cf)cmathcal E(C_f) and cmathcalE(H)cmathcal E(H) be the finite sets of integer multiples introduced in the paper. Newton-polytope determination conjecture. For almost all ff with Hf=HH_f=H, where all coefficients vary and the polynomials are ordered by coefficient size, we have

G(Cf)=G(H)andcmathcalE(Cf)=cmathcalE(H).G(C_f)=G(H)\quad\text{and}\quad cmathcal E(C_f)=cmathcal E(H).

Equivalently, D(Cf)infD(C_f)^{\mathrm{inf}} is typically entirely determined by HfH_f. The claim formalizes the idea that the degrees occurring infinitely often should usually depend only on the Newton polytope, although the supplied text does not state its resolution.
