Explore New Method of Image Quadratic Search Based on Image Content 基于内容的图像二次检索新方法探究
In this paper, the quadratic polynomial function is used to reconstruct the response surface in search of the possible breakdown point, and the BP neural network is adopted to reconstruct the response surface around the possible breakdown point, fitting the limit state function. 针对这种情况,文章采用二次多项式函数重构响应面来寻求设计验算点;然后在设计验算点附近,采用BP神经网络重构响应面,拟合极限状态函数;
The quadratic interpolation method with the constraints approximated by quadratic polynomials is used in the one-dimensional search. 采用了以二次多项式逼近约束函数的二次插值法来进行一维搜索;给出了内罚函数法中所用到的各个收敛准则;
The subsystem levels were optimized by SQP ( sequential quadratic programming), and the system level by the hybrid search algorithm. 同时各学科级采用序列二次规划法,系统级采用混合算法寻优。
