Abstract:

A novel method of function minimization which combines the power of the diagonal approximation to the normal matrix with conjugate directions is described. This method approaches closer to the local minimum than the methods which are commonly used in macromolecular refinement. The weaknesses of the current methods are analyzed to explain the advantage of the conjugate direction method.
