Table 12. Time taken and percentage converged for Example 2 using the ML+Lp-Search method.
ML+Lp-Search is considerably faster than default Lp-Search performance. Converged refers to the fraction of time that Lp-Search converges to the true lattice parameters in 20 minimizations of 50 000 iterations. VR is the search space volume ratio for each lattice parameter bound.
| Lattice parameter range | Converged | 〈Time〉 (s) | σ(Time) (s) | VR |
|---|---|---|---|---|
| 10% bound | 1.0 | 37.00 | 27.79 | 7239 |
| 20% bound | 1.0 | 97.97 | 91.53 | 920 |
| 50% bound | 1.0 | 847.22 | 860.60 | 59 |
| (3–2d max) | 1.0 | 3989.61 | 3297.83 | 1 |
