二聚体方法是一种计算鞍点的无Hessian算法。我们使用自动步长选择的线搜索机制以及预处理功能来增强该方法。我们证明了局部线性收敛。一系列的数值测试表明显着的性能增益。
The dimer method is a Hessian-free algorithm for computing saddle points. We augment the method with a linesearch mechanism for automatic step size selection as well as preconditioning capabilities. We prove local linear convergence. A series of numerical tests demonstrate significant performance gains.
