Tracing the history of a solution and a nonsolution trial for scorpion toxin II as a function of Shake-and-Bake cycle. (a) Minimal-function figure of merit, and (b) number of peaks closer than 0.5 Å to true atomic positions. Simple peak picking (200 or 0.4Nu peaks) was used for 500 (Nu) cycles, and 500 peaks (Nu) were then selected for an additional 50 (0.1Nu) dual-space cycles. The solution (which had the lowest minimal-function value) was then subjected to 50 cycles of Fourier refinement.
