  • 简介:在顺序的拍卖,衰退价格的现象经常被观察,在理论,罐头它被supermartingale代表。这份报纸采用投标人价值可以在阶段上改变,普通priors被留下的投标人顺序调整的观点。衰退价格顺序能被在拍卖之间的普通priors的调整解释,这被显示出。普通priors的调整被随机的订单描绘。为一个supermartingale价格序列的足够、必要的条件被导出。

  • 简介:顺序的点树提供最先进的技术因为使点模型变为,由重排层次根据为快显示在GPU上跑的几何错误顺序指。这篇论文论述一个看法依赖者方法由在层次点的顺序的表嵌入层次树结构扩充顺序的点树。由方法,二种索引被构造便于近从主要在一份订单显示到远方的点;从对粗糙好。作为结果,不可见的点能为硬件加速在高效率view-dependently被挑选,;同时,顺序的点树的优点能仍然充分被拿。因此,新方法能跑得比常规顺序的点树快得多,;当目标拥有复杂吸藏关系时,加速能高度特别地被支持;因为不可见的点将在在更好的层次的点的一个高百分比,仔细看了。
