A dataset for suggesting variable orderings for cylindrical algebraic decompositions
收藏资源简介:
This dataset contains the running time and the number of cells of the CylindricalAlgebraicDecompose command in the RegularChains library of Maple under all possible variable orderings for more than 20K number of randomly generated polynomial systems of three variables (12141 examples) and four variables (11800 examples). For each example, the running time of the worst ordering is at least twice that of the best variable ordering. It can be used for benchmarking and designing heuristic methods and machine learning models for suggesting variable orderings for CADs. Please refer readme.txt for more detailed information of the dataset and the tiny difference between v1, v2 and v3.
本数据集涵盖超过2万个随机生成的多项式系统,包含三元多项式系统(共12141个示例)与四元多项式系统(共11800个示例),统计了Maple软件正则链(RegularChains)库中柱面代数分解(CylindricalAlgebraicDecompose,以下简称CAD)命令在所有可能变量排序下的运行时长与胞腔数量。对于每个示例而言,其最差变量排序对应的运行时长至少为最优变量排序的两倍。该数据集可用于基准测试,以及设计用于为CAD任务推荐变量排序的启发式方法与机器学习模型。如需了解本数据集的详细信息以及v1、v2、v3版本间的细微差异,请参阅readme.txt文件。
