Entries for these benchmarks must record the average number number of force calls as force_calls in benchmark.dat, the standard error of the mean force calls as force_calls_mean_error, the average fraction of saddles that are connected to the initial minimum as fraction_connected, the average total number of saddle searches total_searches, and the average number of unique saddles found unique_saddles.
This benchmark measure the effiency of finding saddles for a Pt heptamer island. The initial geometry is provided in con and POSCAR formats. The potential energy is given by a Morse potential: \[ V(r) = D(e^{-2\alpha(r-r_0)} - 2 e^{-\alpha(r-r_0)}) \] with $D=0.7102$, $\alpha=1.6047$, and $r_0=2.897$.
The goal of the benchmark is to deterimine how many force calls it takes to find the 27 connected saddles with a barrier below 1.5 eV. A individual saddle search is considered complete when the norm of the force is reduced to below 10^{-3} eV/Angstrom.
In the table below ρ is the fraction of saddles found that were connected to the initial minimum, N_{u} is the number of unique connected saddles, N_{s} is the total number of saddle searches, and N_{f} is the total number of force calls.
