Predicting crystal structures with data mining of quantum calculations.

Predicting and characterizing the crystal structure of materials is a key problem in materials research and development. It is typically addressed with highly accurate quantum mechanical computations on a small set of candidate structures, or with empirical rules that have been extracted from a large amount of experimental information, but have limited predictive power. In this Letter, we trans...

Predicting peptide structures using NMR data and deterministic global optimization

The ability to analyze large molecular structures by NMR techniques requires efcient methods for structure calculation. Currently there are several widely available methods for tackling these problems, which, in general, rely on the optimization of penalty-type target functions in order to satisfy the conformational restraints. Typically, these methods combine simulated annealing protocols with...

Predicting Molecular Crystal Structures Biogeometry

Since about 10 years ago, computer algorithms are available that can generate probable structures of molecular crystals [1]. Such predictions are important for virtually any scientific research and industrial application that deals with molecular crystals. The modified Monte-Carlo Simulated Annealing method [2] of PI Robert Gdanitz (NCAT, Physics) is, in fact, the first method that allows for a...

Predicting polymeric crystal structures by evolutionary algorithms.

The recently developed evolutionary algorithm USPEX proved to be a tool that enables accurate and reliable prediction of structures. Here we extend this method to predict the crystal structure of polymers by constrained evolutionary search, where each monomeric unit is treated as a building block with fixed connectivity. This greatly reduces the search space and allows the initial structure gen...
