Table 13. Time taken and percentage converged for Example 3 using the ML+Lp-Search method.

ML+Lp-Search is considerably faster and converges more often than default Lp-Search. 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	44.8	38.5	404
20% bound	0.85	185.6	142.5	101
50% bound	0.50	354.2	155.1	16
(3–2d max)	0.0			1
