Benchmark Results

Benchmark data

For the calculation, full benchmark set was used (25168 optimized geometries, plus relative energies of 2005 molecules). Detailed of the molecule selection can be found here: release-1-benchmarking/QM_molecule_selection

(1) Comparison of objective values from single point calculations on benchmark full set

Two types of benchmarks were done to compare the performances: (1) QM vs MM optimized geometries and (2) the relative energies between conformers at “QM optimized geometries”. The final objective function value(X2) from FB single point calculation gives a brief overview of the agreement between QM and MM. The lower X2 is, the better the force field reproduces QM structures and energetics.
