SMACT is a composition-based screening tool . It generates a search space, or a set of element combinations, that is screened using chemical filters. Oxidation states, charge neutrality, and electronegativity can be considered to screen for candidates that make "chemical sense." If the overall charge of a composition is neutral, then SMACT will consider it valid. The original checker however does not consider the countless combinations of oxidation states for metal alloys. To account for this, materials composed of all metal elements are assumed valid in the checker. To perform this, we implement a function called smact_validity(). The Boolean values for each of the predicted compositions are under the is_valid column in Table C. DiSCoVeR DiSCoVeR stands for Descending from Stochastic Clustering Variance Regression. This algorithm is a conglomerate of multiple tools (as shown in Fig. ) that are ultimately used for the screening and assessment of the superconductive compositions. "DiSCoVeR screens candidates that have a high probability of success while enforcing -through the use of novel loss functions -that the candidates exist beyond typical materials landscapes and have high performance.
