英文摘要：
In this paper, we propose an approach of afflne scaling interior discrete conjugate gradient path for solving nonlinear equality systems subject to bounds on variable. By constructing preconditioned discrete conjugate gradient path, we obtain an iterative search direction. By combining interior backtracking line search, we find an acceptable trial step length. The search direction and step length which are obtained possess good properties. The global convergence and local convergence rate of the proposed algorithm are established under some reasonable conditions. Furthermore, the numerical results indicate the effectiveness of the algorithm.
