Search - non linear conjugate algorithm

Search - non linear conjugate algorithm - List

[CSharp] 抛物线法 DL : 0: 上述算法的终止准则为H终止准则。要求编写通用程序。关于函数的要求：直线搜索所计算的函数自己任选。共轭梯度法所计算的函数：①计算一个正定二次函数（至少是4元函数）；②至少计算一个非二次函数（至少是5元函数）。非线性最小二乘问题的修正Gauss-Newton法所计算的函数：至少计算一个非线性函数（至少是5元函数）。乘子法所计算的问题：等式约束、不等式约束要求至少各有一个。问题可在教材或其它参考书中任意选取。程序自行编写（禁止采用调用现成软件的方式），编程语言自选。 -above algorithm criteria for the termination of H termination criteria. Requests for common procedures. The demands on function : linear search function by calculating their options. The conjugate gradient method by calculating function : calculate a definite quadratic function (at least four yuan function); calculated at least one non-quadratic function (at least five yuan functions). The nonlinear least squares problems that Gauss-Newton method by calculating function : at least a nonlinear function computing (at least five yuan functions). Multiplier Method calculation problem : identity bound inequality constraints have required at least one. Problems in reference books or other materials were selected at random. Self-preparation procedure (called ban on the use of existing software)
