摘要

CVC4是可满足模理论(SMT)的求解器。本教程旨在为参与者提供SMT的概述,描述CVC4的主要功能,并通过使用CVC4的深入示例来演示如何使用SMT求解器解决实际问题。我们将详细描述CVC4内部的各个方面,包括它的体系结构、处理量词的能力、有限模型查找器和线性算法求解器。我们将展示软件和硬件验证问题的示例,以及如何在CVC4中对这些特性进行编码和处理。参与者只需要对SMT有一个基本的了解。本教程将让普通用户体验在SMT中编码复杂的现实问题,并有效地使用CVC4来解决这些问题。参与者将了解现代SMT求解器内部发生的事情以及在使用它们时出现的一些实际问题。CVC4由纽约大学和爱荷华大学联合开发,在开源许可下可免费用于研究和商业用途。本教程的组织者都是CVC4的架构师和实现者,并且在SMT领域拥有丰富的专业知识。

A tour of CVC4: How it works, and how to use it
CVC4 is a solver for Satisfiability Modulo Theories (SMT). This tutorial aims to give participants an overview of SMT, describe the main features of CVC4, and walk through in-depth examples using CVC4 to demonstrate how to solve real problems with an SMT solver. We will provide a detailed description of various aspects of CVC4's internals, including its architecture, its capacity for dealing with quantifiers, its finite model finder, and the linear arithmetic solver. We will show examples of software and hardware verification problems, and how they are encoded and handled by these features in CVC4. Participants are expected to have only a basic knowledge of what SMT is. This tutorial will give casual users a taste of encoding complex, real-world problems in SMT and effectively using CVC4 to solve them. Participants will be left with some knowledge of what goes on inside a modern SMT solver and some of the practical issues that arise in using them. CVC4, jointly developed at New York University and the University of Iowa, is freely available for both research and commercial use under an open-source license. The organizers of this tutorial are all architects and implementors of CVC4 and have extensive expertise in the area of SMT.
