All created structures were used for DFT single-point calculations, yielding a training dataset of 64k configurations with Si/Ge ratios ranging from 0.3 to 9. This dataset is publicly available under: 10.5281/zenodo.11551686. Since our focus is on simulations of EQ structures that mostly show force magnitudes of a few eV/Å, we excluded all structures with forces higher than 15 eV/Å. The DFT simulations used the Vienna Ab initio Simulation Package (VASP, version 5.4.4) 22 along with the PBE exchange-correlation functional and the D3 dispersion correction with Becke-Johnson (BJ) damping . We employed the Projector Augmented-Wave (PAW) method with the standard (recommended) potentials and a plane-wave energy cutoff of 400 eV. For every unit cell, the k-point density was not lower than 0.1 Å -1 along each reciprocal lattice vector.
