Ar, but displays fewer features than the exact w λ→∞ (r). This would be likely fixed if one designs a more sophisticated σλ→∞ (r), by e.g., letting it vary between 1/2 and 0.8 (maximum σ value from the UEG) and ensuring that it satisfies the scaling invariability constraint of Eq. 20 (this constraint is trivially satisfied in MRF-half, as σ is always 1/2).
