In Figure we show the distribution of the formation energy and bulk modulus for atomic configurations by partitioning the data according to its initial regular BCC, FCC, and HCP crystal structures before applying geometry optimization. From the first row, we notice that the possible range of the formation energy is well represented by a large number of atomic configurations for each portion of the dataset based on the initial regular solid phase, although the distribution of atomic arrangements seems skewed towards energy values that are smaller in magnitude. Moreover, the scatter plots on the second row show that the formation energy is strongly correlated with the chemical composition of the alloy. From the third row, we notice that the distribution of values of the bulk modulus has noticeable high peaked modes, indicating the values of the bulk modulus that occur most frequently across the possible set of atomic configurations. From the last row, we conclude that the dataset does not suggest any clear correlation between the value of the bulk modulus and the chemical composition of the alloy. These widespread scatter plots already suggest that predicting the bulk modulus as a function of the atomic arrangement may be a more challenging task than predicting the formation energy.
