用ASP求解Hamilton圈问题的编码选择

Encoding Selection for Solving Hamiltonian Cycle Problems with ASP

University of Kentucky(肯塔基大学)

Liu Liu, Miroslaw Truszczynski

摘要:

在ASP中,搜索和优化问题通常具有替代的等效编码。通常情况下,当对广泛的问题实例进行评估时,没有一个比其他方法更好。我们声称,可以提高解决能力的ASP使用机器学习技术来选择编码可能会在一个给定的实例上表现良好。我们通过研究哈密顿循环问题来证实这一说法。我们提出了几个等价的编码问题和几类硬实例。我们建立模型来预测每个编码的行为,然后表明,使用学习到的性能预测器为给定实例选择编码会导致显着的性能增益。

英文摘要:

It is common for search and optimization problems to have alternative equivalent encodings in ASP. Typically none of them is uniformly better than others when evaluated on broad classes of problem instances. We claim that one can improve the solving ability of ASP by using machine learning techniques to select encodings likely to perform well on a given instance. We substantiate this claim by studying the hamiltonian cycle problem. We propose several equivalent encodings of the problem and several classes of hard instances. We build models to predict the behavior of each encoding, and then show that selecting encodings for a given instance using the learned performance predictors leads to significant performance gains.
