We present a comparison between the modified Monte Carlo algorithm (MMCA) and a recently proposed ray-tracing algorithm named as photon-tracing algorithm. Both methods are compared exhaustively according to error analysis and computational costs. We show that the new photon-tracing method offers a solution with a slightly greater error but requiring from considerable less computing time. Moreover, from a practical point of view, the solutions obtained with both algorithms are approximately equivalent, demonstrating the goodness of the new photon-tracing method.
我们对改进的蒙特卡罗算法（MMCA）和最近提出的一种名为光子追踪算法的光线追踪算法进行了比较。根据误差分析和计算成本对这两种方法进行了详尽的比较。我们表明，新的光子追踪方法提供的解决方案误差略大，但所需的计算时间要少得多。此外，从实际角度来看，两种算法获得的解决方案大致相当，这证明了新的光子追踪方法的优势。
