Workflow of the current study: (a). data collection and processing; (b). training, testing and evaluation of tree-based models; (c). classification of optimization models (full-length image is provided in Section “Optimisation techniques”) and selection of best optimization model (models in red font were selected for this study) for obtaining our objective; (d). generated novel compositions; (e). comparison of the predicted hardness with Thermo-Calc ones for validation; hardness of novel HEA (Al6.25Cu18.75Co25Fe25Ni25) prepared in the earlier study was measured and compared with Thermo-Calc one for reinforcing the present study.
