Sheldrick, G. M., Gilmore, C. J., Hauptman, H. A., Weeks, C. M., Miller, R. and Usón, I.  International Tables for Crystallography (2012). Vol. F, Section 16.1.4.3, p. 418 [ doi:10.1107/97809553602060000850 ]
Parameter shift 16.1.4.3. Parameter shift In principle, any minimization technique could be used to minimize by varying the phases. So far, a seemingly simple algorithm, known as parameter shift (Bhuiya & Stanley, 1963), has proven to be quite powerful and efficient as an optimization method when used within the Shake-and-Bake ...
