算法程序分Nelder0.m和Opt-Nelder.m其中子程序Nelder0.m用于二维空间上的多边形最优化逼近.对于大于2维的情形,可以通过若干次二维迭代计算求出最优值.Opt-Nelder.m可求解若干维变量的最优化问题(The algorithm of Nelder0.m procedure and Opt-Nelder.m which is used for subroutine Nelder0.m approximation polygon optimization of two-dimensional space. For more than 2 dimensional case, through several two-dimensional iterative calculation to derive the optimal value of.Opt-Nelder.m optimization problem solving some dimension)
