2) absolute value equation 绝对值方程 1. Absolute value equation(AVE) Ax-|x|=b,A∈R~(n×n),b∈R~n is a special class of nonlinear equations and it is NP-Hard. 本论文主要研究了绝对值方程的求解问题,根据其半光滑的特性,提出了一个广义牛顿算法,该算法在迭代过程中使用了半光滑牛顿步和...
Absolute value equationsAbsolute value inequalities The geometrical meaning of |x − a| THIS SYMBOL |x| denotes the absolute value of x, which is the number without its sign. |+3| = 3. |−3| = 3. We could say that the absolute value of a number is its purely arithmetical value....
In this paper, we focus on absolute value equations of linear and quadratic expressions, by examining various cases, presenting different methods of solving them by graphical representation, exhibiting the advantage of using dynamic software such as GeoGebra in solving them, and illustrating some ...
By utilizing an equivalence relation to the linear complementarity problem (LCP) we give existence results for this class of absolute value equations (AVEs) as well as a method of solution for special cases. We also give nonexistence results for our AVE using theorems of the alternative and ...
x−2+x+7=11, x=3. ②When x−2<0 and x+7⩾0, −7⩽x<2, 2−x+x+7=11, there is no solution. ③When x+7<0, x<−7, 2−x−x−7=11, x=−8. ∴ x=3 or x=−8. (2) When 2x−7⩾0, x⩾72, 2x−1−(2x−7)=0, there is no soluti...
In this paper, we study the optimum correction of the absolute value equations through making minimal changes in the coefficient matrix and the right hand side vector and using spectral norm. This problem can be formulated as a non-differentiable, non-convex and unconstrained fractional quadratic ...
