本文提出了一种新的函数极小化方法,该方法将对角逼近法阵的幂与共轭方向相结合。该方法比通常用于大分子精细化的方法更接近局部最小值。分析了现有方法的不足,说明了共轭方向法的优越性。
A novel method of function minimization that 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 that are commonly used in macromolecular refinement. The weaknesses of the current methods are analyzed to explain the advantage of the conjugate-direction method.
