简介：这篇论文描述有效数据结构，也就是索引的P树，块P树，和索引块P树(或IP树，BP树，和IBP树，分别地为短)为在一个通用离散事件模拟系统维持未来事件，并且在事件地平线原则下面学习他们的事件集合算法的表演。为比较原因，一些著名事件集合算法被选择了并且学习，也就是说theDynamic堆和P树算法。到进给算法并且与另外的选择算法允许比较的建议事件的表演的获得卓见，他们以一个试验性的方法在许多条件下面被测试。为Holdoperation的实行需要的时间为估计算法的平均时间复杂性作为这项措施被花。BP树算法和IBP树算法与所有尺寸和他们的表演的事件集合表现很好的Theexperimental结果表演几乎独立于随机的分布。
