Used perturbed method and making inexact generalized gradient projection with cone, perturbed generalized gradient projection method is proposed. the field of the algorithm is extended. numerical experiments show that the method is effective. secondly, using the trust region form and the pseudo - directional derivative of minimax problem, we propose the trust region form of minimax problem
對信賴域法作了進一步的研究，藉助minimax問題的偽方向導數，構造出其信賴域二次模型，並結合非單調策略，給出求解minimax問題的簡單易行的信賴域演算法。 -
A few practical cone - beam reconstruction algorithms, including feldkamp, cross - convolution method and cone - convolution method are analyzed. some useful conclusion is drawn by comparing and evaluating the reconstruction result which comes from actual projection data
