GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 3.3 GNGTS 2024 We use ShellSet’s grid search model generator to automatcally search the defned 2D parameter space for an optmal model. The grid search contains 45 models, generated over 3 levels startng with 9 models before generatng a further 9 within the cell of each of the best 2 models at the frst and second levels, see Fig. 1. Among the 45 models we fnd 8 models with an equal or improved (lower) geometric mean score. These 8 models can be seen in Tab. 1, along with the original score for the best model of Bird 2008 (Earth5-049) and a re-run to account for newer sofware accuracy (New Earth5-049).
