AI总结:

提出一种包含乘法与除法对加法和减法分配律的区间算术新框架,从而避免包裹效应和数据依赖,并展示了在矩阵特征值计算、对称矩阵求逆和优化中的应用。

摘要:

本文提出了区间算术中一些非常有前景的结果,这些结果允许构建定义良好的算术,包括乘法和除法对加法和减法的分配律。因此,它允许在区间上构建所有代数运算和函数。这将完全避免包裹效应和数据依赖。在面向对象的编程语言Python中展示了矩阵特征值计算、对称矩阵求逆以及优化的一些简单应用。

英文摘要:

In this paper we propose some very promissing results in interval arithmetics which permit to build well-defined arithmetics including distributivity of multiplication and division according addition and substraction. Thus, it allows to build all algebraic operations and functions on intervals. This will avoid completely the wrapping effects and data dependance. Some simple applications for matrix eigenvalues calculations, inversion of symmetric matrices and finally optimization are exhibited in the object-oriented programming language python.
