This core course is about techniques for analyzing and understanding
software artifacts. Ultimately, the goal of this area of study is to
improve the quality of software. We will cover three
related areas of programming languages research:
analysis, the name for any automatic technique for reasoning about
program source code. We will study data flow analysis and type
systems, and more briefly theorem proving. Model checking will be
covered by CMSC 630, offered in Spring 2007.
- Formal systems for describing languages and
programs, including lambda calculus and axiomatic, denotational, and
- Programming language features and
how they affect software, including imperative, functional, and
Prerequisite: CMSC 430 or equivalent. Most of the material
covered in a typical compilers course (CMSC 430) will not be used in
this class, so even if you have not taken such a course you may be
fine in 631. Contact the instructor if you are interested
in taking 631 but aren't sure if you have the background.
Grading and Expectations
Subject to change, especially until the start of the semester.
The final course grade will be made up of the following components:
- Homework and Programming Assignments (30%) During the
semester, there will be several short written homework assignments;
a few programming assignments; and assignments using the Coq
- Project (35%) You will be expected to complete a
substantial research project during the semester. Projects may be
completed individually or in pairs. For more details, see the
- Participation and Presentation (10%) You will present your
project to the class, and if there is time, we will include student
presentations of existing papers (probably on static analysis tools).
Here are the criteria for grading
presentations. You will also be graded on contributions to class
- Final Exam (25%) This course will include a final exam,
which will cover material from the homeworks, programming assginments,
and other lecture material.
Written assignments are due at the beginning of class on the due date.
Programming assignments (or assignments developed in Coq) are due at
midnight on the due date. Neither written nor programming assignments
may be turned in late. If you cannot make a due date because of
extenuating circumstances, or because it conflicts with a religious
holiday, please inform the instructor as soon as possible.
The college policy on academic dishonesty is strictly followed. All
graded materials must be strictly individual efforts. Projects may
include collaboration as permitted by the instructor.
