查询词典 iterative computation

In the computation of initial value of QP,this paper proposes bpp,entropy and gradient as an estimate of the complexity of the image.

在初始QP值的计算上，提出了利用基于bpp、熵和梯度的图像复杂度对初始QP值进行估计的方法。

To compute the solution to the nonlinear equation of pressure in the Riemann problem for the pressure grdient equations, the Godunov scheme gives a reasonable approximate value for the exact solution. By using the Newton-Ruphson iteration method and some necessary computation, we get the inter-cell numerical flux directly.

为求压差方程黎曼问题中关于压力的非线性方程的解，Godunov格式给出一个合理的初始近似值，利用Newton迭代法和一些必要的计算得到格式中的数值流。

The Laplace modified method is used in time step and the backward Euler scheme and Crank- Nicolson scheme are developed. By applying the collocation method for the nonlinear term, the computation time is greatly saved.
