چکیده
This lecture provides theoretical background required for static program analysis, and presents the idea of chaotic iterations. Abstract interpretation was introduced in the seminal paper by Cousot and Cousot [1]. The main idea is to map each of the program states to an abstract state. An abstract state may represent more than one concrete state. Using the abstract states, it will be easier to analyze how running the program changes the program state. If the resulting abstract state corresponds only to concrete states that are valid (i.e., satisfy the required properties), we can be sure that the program is valid and has no bugs. However, since the abstract states only approximate the running of the program, it is possible that our analysis will report bugs that do not exist. We say that an analysis that cannot miss any bugs is sound, but if the analysis can report non-existent bugs, we say that it is not complete.

Reminder concerning the final: The exam will be Tuesday May 9, at the usual class time. It will be “closed-book” (no books, no lecture notes), however you may bring two sheets of notes (8.5 × 11, both sides, write as small as you like). You are responsible for the material in Sections 1-6 of the lecture notes, and in Homeworks 1-6. See the separate handout for further discussion of what to expe...
