论文名称：Simultaneous Arrival Matching for New Spatial Crowdsourcing Platforms

推荐理由：近年来，3D空间众包平台开始流行，即用户和工人一起前往指定的工作地点进行服务，如趣运动、南瓜网等。在3D空间众包平台上，如何匹配用户与合适的工人和工作场所是一个经典的问题。现有的研究都忽略了分配到同一工作场所的工人和用户应该几乎同时到达，而这个问题在现实生活中普遍存在。因此，在本文中，作者提出了新颖的同步到达匹配（Simultaneous Arrival Matching，简称SAM）问题，其中工人和用户在给定的容忍时间内到达指定的工作地点。为解决SAM，该研究设计了滑动窗口算法和阈值扫描算法。同时，在真实数据集和合成数据集上的实验显示了上述算法的有效性和高效性。
