| Aims |
|
To understand what a correct algorithm is. To gain knowledge of designing correct algorithms and proving their correctness hand- in-hand. To learn the methods of program vverification and validation. To become used with building correct programs from specifications.
To acquire a modern programming style. |

I. The theory of program correctness (4 lectures)
- Program Specification - Floyd method for prooving correctness - Hoare axiomatisation method - Dijkstra: the weakest precondition. - Stepwise refinement from specifications - The Evolution of the concept of programcorrectness. The Contribution of Floyd, Hoare, Dijkstra, Gries, Droomey, Morgan II. Verification and validation: (3 lectures) - the concepts verification and validation; - the verification methods; - program inspection; - symbolic execution; - testing and debugging; - documentation. III. Program testing: (3 cursuri) - the concept of Program testing; - unit testing: testing criteria, blackbox and whitebox testing; - types of testing: integration T., system T., regression T., acceptance T. - testing automatizing IV. Model checking (2 lectures) V. Comparing the verification methods (2 lectures) - correctness-inspection-testing-symbolic execution - Cleanroom. Program Quality - The consequences of the theory of program correctness on programming. Programming style. 9. Consequences on programming activity. Programming rules. |

| Assessment |
|
Each student must read a published research paper and present it at a seminary. He will obtain a mark for the presentation given to the seminary, for the way he expressed the ideas, and for his activityy in the seminaries (mark R). The activity ends with a written examination (mark E). The final mark is the average of R and E, i.e. F=(R+E)/2 |
