The optimization problem was formulated as a multiple-stage optimal control problem and solved by a forward and backward iterationloop.
整个最优化问题被描述成一个多阶段系统优化控制问题,通过一个向前和向后的迭代循环解决。

In the general ellipse - generating algorithm for raster - pixel, there are always multiplication and square root operating in the main iterationloop, so the calculating cost is more expensive.
