| 摘 要： | 提出求解有限维变分不等式的熵函数法.分析了算法的性质,在一定条件下证明了熵函数逼近问题解的存在性,并证明熵函数法逼近方程组产生的点列的每个极限点均为有限维变分不等式的解.在一定条件下,熵函数法全局收敛且具有二次收敛率.数值算例表明了方法的有效性.

| Abstract: | Based on brief review of the numerical methods for variational inequalities,an entropy method for solving variational inequalities is proposed.The properties of the method are analyzed.On a certain condition,the existence of entropy method is proved.It is proved that the limited point generated by entropy method is unique solution of variational inequalities.On a certain condition,the global convergence is proved,and its rate is square.The numerical experiments indicate that the method is efficient. |
