摘要:
为了研究广义绝对值方程的求解问题,通过构造极大熵函数和新的区间算子,给出了一个求解广义绝对值方程的区间极大熵算法。该算法能同时求出广义绝对值方程近似解和估算其近似解的误差限,并在一定条件下,证明了算法的收敛性且收敛速度至少是线性的。理论分析和数值结果均表明提出的算法是有效的。

Abstract:
This paper is concerned with the generalized absolute value equations. Based on maximum entropy method and a new interval operator, a new interval algorithm is proposed. Furthermore, the estimation error between the exact solution and the approximate solution has been given in the analysis. Its convergence and linear convergent rate are proved under an assumption. Theoretic analysis and numerical results show that the method is effective.
