Grid search strategy

Weber, P. C. (1990). A protein crystallization strategy using automated grid searches on successively finer grids. 

To approximately locate the global minimum i.e., to obtain a good quality crystal structure solution) in a reasonable amount of time, grid search methods should be replaced by the stochastic ones, based on a random sampling of the parameter space. This technique, called Monte Carlo MC), has been widely used in other scientific fields to simulate the behavior of complex systems. Its application to crystal structure determination from powder diffraction data has been developed by many authors the main strategies are outlined below. 

Side-chain prediction methods can be classified in terms of how they treat side-chain dihedral angles (rotamer library, grid, or continuous dihedral angle distribution), potential energy function used to evaluate proposed conformations, and search strategy. These factors are summarized in Table...
