在之前的论文中,我们介绍了几何算法中数据简并问题的通用解决方案。该方案使用起来很简单:符合我们要求的算法只需使用规定的黑盒进行多项式评估,即可实现数据的符号扰动。在本文中,我们引入了无穷小扰动的概念,并表明我们的方法相对于此类扰动是一致的。
In a previous paper, we introduced a generic solution to the problem of data degeneracy in geometric algorithms. The scheme is simple to use: algorithms qualifying under our requirements just have to use a prescribed blackbox for polynomial evaluation in order to achieve a symbolic perturbation of data. In this paper, we introduce the concept of an infinitesimal perturbation and show that our method is consistent relative to such perturbations.
