松弛方法和某些预处理共轭梯度技术之间的比较已经取得了解决所产生的线性方程组的线性Poisson-Boltzmann方程的有限差分形式。Meijerink和货车der沃斯特的不完全Cholesky共轭梯度（ICCG）方法已被发现上级松弛方法，在速度上至少有两倍的改进，而存储量仅增加50%。
Comparisons have been made between relaxation methods and certain preconditioned conjugate gradient techniques for solving the system of linear equations arising from the finite-difference form of the linearized Poisson-Boltzmann equation. The incomplete Cholesky conjugate gradient (ICCG) method of Meijerink and van der Vorst has been found to be superior to relaxation methods, with at least a factor of two improvement in speed, and only a 50% increase in storage.
