项目摘要
Based on a proposed "approximate ideal", we constructed a theory of approximate Groebner basis, clarified the instability of Buchberger's algorithm on floating point numbbers using a developed subresultnat-like theory, and proposed an algorithm of approximate Groebner basis by stabilizing Buchberger's algorithm.We also proposed a concept of "approximate singular system" as a multivariate polynomial ideal whose dimension is decreased by a purturbation, and presented an algorithm which recovers the dimension. Applying this operation to algebraic systems of approximately singular type, we proposed a well-conditioning method for such systems. Furthermore, we proposed an error suppressing method and a characteristics extracting method for solving parametric sparse linear systems.
基于提出的“近似理想”,构造了近似Groebner基的理论,利用推广的类次结果理论证明了Buchberger算法在浮点数上的不稳定性,并通过稳定化Buchberger算法提出了近似Groebner基的算法,同时提出了“近似奇异系统”的概念,即通过扰动降维的多元多项式理想,并给出了一个恢复维数的算法.将这一运算应用于近似奇异型代数系统,提出了这类系统的一种良条件化方法。在此基础上,提出了求解参数稀疏线性方程组的误差抑制方法和特征提取方法。
