利用广义投影技术,提出了一个求解非线性不等式组的新算法.在算法的每一次迭代中,搜索方向仅由一个公式即可产生,从而计算量相对较小,并且在相对较弱的假设条件下,算法具有全局收敛性和有限步终止性.最后的数值试验表明提出的算法是有效的.
This paper,using the technique of generalized projection,presents a new algorithm for solving systems of nonlinear inequalities. At each iteration,the search direction is yielded by only one new explicit formula and the computing cost can be reduced. Under relatively weaker assumptions,the global convergence and finite termination can be obtained. The final numerical results show the algorithm is effective.
