区间分析作为一种求非线性方程组全部解的计算方法,已广为人知。为了提高区间分析的计算效率,有必要发展一种强有力的判别方法来判别解在给定区域内的不存在性。本文提出了一种新的不存在性检验方法,它比传统的不存在性检验方法更有效。这里提出的基本思想是将常规检验应用于函数的线性组合。提出了有效的线性组合,使不存在性测试非常强大。使用所提出的技术,所有的非线性方程组(包括100个非线性方程组的系统和具有强非线性的描述晶体管电路的系统)的解决方案可以非常有效地找到。
As a computational method to find all solutions of nonlinear equations, interval analysis is well-known. In order to improve the computational efficiency of interval analysis, it is necessary to develop a powerful test for nonexistence of a solution in a given region. In this paper, a new nonexistence test is proposed which is more powerful than the conventional test. The basic idea proposed here is to apply the conventional test to linear combinations of functions. Effective linear combinations are proposed which make the nonexistence test very powerful. Using the proposed techniques, all solutions of nonlinear equations (including a system of 100 nonlinear equations and a system with strong nonlinearity which describes a transistor circuit) could be found very efficiently.
