p—~4He参数化散射振幅有关参数的拟合,是一个非线性最小二乘问题。本文介绍用最优化方法中的模式搜索法(Hooke-Jeeve方法)拟合Tp=0.2Gev—1.73Gev的p—~4He散射振幅的算法、结果以及计算中有关问题的讨论。
The fitting of the parameters of p- ~ 4He parameterized scattering amplitude is a nonlinear least square problem. In this paper, we discuss the algorithms and results of fitting the p- ~ 4He scattering amplitudes of Tp = 0.2Gev-1.73Gev using the pattern search method (Hooke-Jeeve method) in the optimization method.
