Supplementary code for the article: Comparative evaluation of the Fast Marching Method and the Fast Evacuation Method for heterogeneous media

<b>Description of the dataset</b>
<p>The evacuation problem is usually addressed by assuming homogeneous media where pedestrians move freely in the presence of several exits and obstacles. From a more general perspective, this work considers heterogeneous media in which the velocity of pedestrians depends on their location. We use cellular automata with a floor field that indicates promising movements to pedestrians and, in this context, we extend two competitive evacuation methods in order for them to be applied to heterogeneous media: the Fast Marching Method and the Fast Evacuation Method. Furthermore, we evaluate the performance that these two methods exhibit over different simulated scenarios characterized by the presence of heterogeneous media. The resulting winning method in terms of evacuation effectiveness is greatly influenced by the particular problem being simulated.</p>

<b>数据集描述</b>
<p>疏散问题的常规研究通常以均匀介质为假设前提，即行人可在多出口与障碍物共存的环境中自由移动。本研究从更具普适性的视角出发，考量介质非均匀的场景——此时行人的行进速度与其所处位置直接相关。本研究采用带有地面场（floor field）的元胞自动机（cellular automata）模型，该地面场可向行人指示更具通行效率的行进方向；在此框架下，我们对两类具有竞争力的疏散方法进行扩展，使其可适配非均匀介质场景：快速行进法（Fast Marching Method）与快速疏散法（Fast Evacuation Method）。此外，我们针对不同的以非均匀介质为核心特征的仿真场景，评估了这两种方法的实际表现。在疏散效能层面表现更优的方法，很大程度上取决于所仿真的具体疏散场景。</p>
