若干变形Hansen-Patrick迭代的点估计

Point estimates on deformation Hansen Patrick iterations

借助于Smale’s点估计 ,研究若干变形的Hansen Patrick迭代的收敛性 ,结果表明 ,当参数p∈ [0 ,2 ] ,α(zo,f)满足一定条件 ,它们比Hansen Patrick迭代计算效率更高。

This paper studies the convergence of the deformation Hansen Patrick iterations such as \$HP\-1\$ ,\$HP\-2\$ by mean of Smale's point estimation. The result is that they are more officient than Hansen Patrick’s when \$p∈\,α(z\-o,f)≤3-22\$ or \$2γτ(1-4γτ)1-2γτ≤α≤3-22\$.
