摘要:

在过去的几十年里,答案集编程(ASP)已经成为声明式问题解决的一个重要范例。这一领域的技术进步是由于使用了共同标准,例如ASP-Core-2语言。虽然ASP的根源在于非单调推理,但人们也努力使ASP与经典的一阶逻辑(FO)相协调。这导致了FO(.)的发展,FO的一个富有表现力的扩展,它允许在纯粹的经典环境中解决类似ASP的问题。这种语言对于已经熟悉FO的领域专家来说可能更容易使用,并且可能更容易与基于经典逻辑的其他形式主义结合。它由IDP推理系统支持,该系统已成功地参加了许多ASP竞赛。然而,在这里,可用于FO(.)的系统数量有限阻碍了技术进步。在本文中,我们的目标是通过一个转换FO(.)的翻译工具来解决这个问题。规范,从而允许ASP-Core-2求解器用作FO(.)也我们目前的实验结果表明,我们的翻译与现成的ASP求解器的组合是有竞争力的IDP系统作为一种解决问题的方式制定FO(。)。正在考虑接受TPLP。

英文摘要:

Over the past decades, Answer Set Programming (ASP) has emerged as an important paradigm for declarative problem solving. Technological progress in this area has been stimulated by the use of common standards, such as the ASP-Core-2 language. While ASP has its roots in non-monotonic reasoning, efforts have also been made to reconcile ASP with classical first-order logic (FO). This has resulted in the development of FO(.), an expressive extension of FO, which allows ASP-like problem solving in a purely classical setting. This language may be more accessible to domain experts already familiar with FO, and may be easier to combine with other formalisms that are based on classical logic. It is supported by the IDP inference system, which has successfully competed in a number of ASP competitions. Here, however, technological progress has been hampered by the limited number of systems that are available for FO(.). In this paper, we aim to address this gap by means of a translation tool that transforms an FO(.) specification into ASP-Core-2, thereby allowing ASP-Core-2 solvers to be used as solvers for FO(.) as well. We present experimental results to show that the resulting combination of our translation with an off-the-shelf ASP solver is competitive with the IDP system as a way of solving problems formulated in FO(.). Under consideration for acceptance in TPLP.
