Their study used a classical simulation algorithm called Gaussian boson sampling to provide a highly efficient way of demonstrating such speedup in solving some well-defined tasks.

他们的研究使用了一种名为高斯玻色子采样的经典模拟算法，在解决一些特定任务时提供了一种高效的方式来证明这种加速。

The reference footage is a real-world video of a water sloshing in a tank, and the other footage that is to be judged is created via a fluid simulation algorithm.

参照视频是液体在水缸中晃荡的真实画面，另一个待评价的画面是通过液体模拟算法创造的。
