提出一个求解无约束最优化问题的自适应信赖域算法,将非精确线性搜索法和信赖域算法相结合,并在适当假设下,证明算法具备全局收敛性.
A trust region method with self-adaptive for solving the unconstrained optimization is proposed.The new method combines trust-region methods with inexact line-search methods.The global convergence of the method is prove under some suitable assumptions.
