... then eliminate some of them, one by one, while maximizing a suitable figure of merit such as The top peaks are ... atoms remain. Use of equation (16.1.5.1) may be regarded as a reciprocal-space method of maximizing the fit to the origin ... function to maximize (Bricogne, 1998). Iterative peaklist optimization provides a higher percentage of solutions than simple peak picking, but ...
