本文研究了求解单调变分不等式问题的一个投影收缩算法.利用何炳生教授的分析手法,给出了新步长,并且证明了在该步长下算法的全局收敛性.初步的数值试验表明了新步长的实用性.
In the article,we study a projection and contraction method for monotone variational inequalities.By using He's proof techniques,we propose a new step length and prove its global convergence.Preliminary numerical tests show the applicability of the new step length.
