trust-region-reflective(TRR)是一种数值优化算法,主要用于非线性最小二乘问题和一些其他的优化问题。TRR算法使用反射性的思想来更新迭代方向,并使用一个信任域来控制迭代步长。TRR算法的主要原理如下: 1.信任域:TRR算法使用一个信任域来控制每次迭代的步长。信任域是一个球形区域,它的半径表示该区域内的解有多好。

The primary advantage of TRAC relative to the state-of-the-art is its computational simplicity which is owed to search space restriction and heuristic approximations with trust-region search. A video of a sample application describing real-time TRAC-based control can be found on the IET's ...
lsqcurvefit. This function implements the trust-region-reflective algorithm in order to solve nonlinear curve-fitting (data-fitting) problems in least-squares sense. I use it because it supports upper and lower bounds constraints. According to the Matlab documentation: ...
