  1. Otherwise, the trust region radius is reduced and a new trial point is selected. it is possible that the region subproblem need to be resolved many times before obtaining an acceptable step, and hence the total computation for completing one iteration might be expensive. this article combines approximate trust region path and nonmonotonic backtracking strategy to solve nonlinear optimization subject to linear inequality constraints, that is, we use approximate trust region path to get the research direction by minimuming quadratical model in the trust region by employing

    本文在求解線性不等式約束優化問題時,將近似信賴域路徑與非單調信賴域方法相結合,即在信賴域半徑內沿近似信賴域路徑得到一極小化二次模型的搜索方向後採用回代法避免重復求解信賴域子問題,在此演算法中當搜索方向不被接受時,就用非單調線搜索技術得到接受步長,定義新的迭代點。
