标题： NumPSLA -- An experimental research tool for pseudoline arrangements and order types

摘要： 我们提出一个程序，用于枚举具有少量伪线的小伪线排列和小点集的抽象顺序类型。 该程序支持对这些结构进行计算机实验，并补充了Aichholzer、Aurenhammer和Krasser的顺序类型数据库。 该系统使得探索12个点的抽象顺序类型以及11条伪线的伪线排列变得可行。 显示英文摘要

摘要： We present a program for enumerating all pseudoline arrangements with a small number of pseudolines and abstract order types of small point sets. This program supports computer experiments with these structures, and it complements the order-type database of Aichholzer, Aurenhammer, and Krasser. This system makes it practical to explore the abstract order types for 12 points, and the pseudoline arrangements of 11 pseudolines.
