Module Learning Outcomes
On successful completion of this module, students will be able to:
- Have gained significant knowledge of mathematical logics (propositional and first order logic) and the Floyd/Hoare logic for software specification. These logics are the basis for software verification, and are a de facto standard in the verification industry;
- Demonstrate the current state-of-the-art in software verification technology, its range of applicability and theoretical limitations, and the necessary tasks required to overcome these limitations where possible;
- Create logic formulas to specify the correct behaviour of programs, including programs implementing well-known algorithms (e.g. binary search), new programs provided to them, and programs they write themselves to solve engineering problems;
- Use the state-of-the-art in software verification tools (e.g. Microsoft Dafny) to mechanically verify software correctness in a team setting;
- Create pencil-and-paper mathematical proofs to manually verify software correctness;
- Design programs that they can then verify correct.
Module Content
- Specification languages and logics;
- Axiomatic program semantics;
- Formal proof systems to verify software and system properties such as propositional, predicate and Hoare logic;
- Proofs by induction;
- Correctness proofs of functional and imperative programs.
Teaching and Learning Methods
Lectures, tutorials, individual assignments, projects. Lectures will be split between presentation of new material and tutorial-style problem solving. Students will have the opportunity to practice the techniques learned in the module, and improve their skills by individual assignments and group project work.
Assessment will be through individual coursework, team project and annual examination.
Assessment Details
Students must submit a meaningful attempt at least in one of the two assignment and two of the three project parts.
