A histogram of the average stress along the length of each of the 945 specimens after optimization, n = 945 (left); a histogram of the average stress at all 100 cross-sections along the length of each of the 945 specimens after optimization, n = 94,500 (right). All stress are normalized to a target stress of 1.00. Thus, stress states that deviate from 1.00 represent a suboptimal structural allocation of biomass
