COMP3141 Software System Design and Implementation COMP3141 软件系统设计与实现 概述 本课程将介绍软件系统开发中设计和实现阶段的严谨和形式化方法。同时还考虑设计的测试和重用。在可能的情况下，将使用可以辅助过程的软件工具。教材将通过案例研究的方式呈现，并要求学生完成一个项目。 报名条件 先修课程: COMP1927 或 COMP2521

COMP3153 COMP9153 Algorithmic Verification 概述 通过标准的软件工程实践，如代码审查、系统测试和良好的软件设计，单凭这些是几乎不可能保证系统的正确性和不存在漏洞的。形式方法社区已经发展出了各种严格的、数学上可靠的技术和工具，可以进行系统和软件的自动分析。这些完全自动的技术通常被称为算法验证。该课程将介绍几种自动验证技术，它们所基于的算法以及支持它们的工具。我们将讨论这些技术所应用的示例，并提供对多个工具的使用经验。 报名条件 先修课程：MATH1081

COMP2111 Assignment 3 Ken Robinson 16th April 2012 Name of assignment: ass3 Due date: 27th April 2012 Assessment: 15 marks Submission: give cs2111 ass3 Library.zip 1 Overview of assignment This assignment extends the tutorial example of a simple library (see 2.4.2). The extensions are: 1. addition of a borrowing limit; 2. addition of a reservation
