Selective Search for Global Optimization of Zero or Small Residual Least-Squares Problems: A Numerical Study
In this paper, we consider searching for global minima of zero or small residual, nonlinear least-squares problems. We propose a selective search approach based on the concept of selective minimization recently introduced ...
The Bayesian Statistical Approach to the Phase Problem in Protein X-ray Crystallography
We review a Bayesian statistical approach to the phase problem in protein X-ray crystallography. We discuss the mathematical foundations and the computational issues. The introduction to the theory and the algorithms does ...
A Fast Newton's Algorithm for Entropy Maximization in Phase Determination
A long-standing problem in X-ray crystallography, known as the phase problem, is to determine the phases for a large set of complex variables, called the structure factors of the crystal, given their magnitudes obtained ...
