rate of convergence

  • 收敛速度：在数值分析中，一个收敛序列向其极限逼近的速度称为收敛速度。该概念多用于最优化算法中；其被定义为一个迭代序列向其局部最优值逼近（假设计算过程收敛，并能达到最优值）的速度，是评价一个迭代法于该问题中发挥的性能的一个重要指标。

英英释义

  • In numerical analysis, the speed at which a convergent sequence approaches its limit is called the rate of convergence. Although strictly speaking, a limit does not give information about any finite first part of the sequence, this concept is of practical importance if we deal with a sequence of successive approximations for an iterative method, as then typically fewer iterations are needed to yield a useful approximation if the rate of convergence is higher.
