Course Description and Syllabus

Formal models of computation, such as finite state automata, pushdown automata, and Turing machines, and their corresponding elements in formal languages (regular, context-free, recursively enumerable). The complexity hierarchy. Church's thesis and undecidability. NP completeness. Theoretical basis of design and compiler construction. Prerequisite: CSE 2100, CSE 2500.

o   Course syllabus


Course Policy

There will be weekly short (5-minute) quizzes, weekly homeworks, a midterm and a final.  The final grade will be computed as follows:

homeworks                        30%
quizzes                               15%
midterm exam                   20%  
final exam                         35%

You are encouraged to discuss homework problems in a group. BUT write your own solutions and state on the paper with whom you have discussed the problems together.   The following criteria are important for judging the quality of a solution:

     correctness (of the whole solution, not just the final answer);
     clarity (being able to state your thoughts clearly using proper terminology);
     conciseness (do not include unnecessary or irrelevant information).

No late homeworks will be accepted.  The grade for two worst homeworks and two worst quizzes will be dropped, which will account for anyone having an illness, emergency, etc.

The University regulations and the CSE 3502 Honor Code will be applied to all cases of plagiarism and academic misconduct.

o   CSE 3502 Honor Code

Between lectures, we will communicate with you via the "announcements" page, linked at the top of this homepage.  Please check for new announcements regularly.

         Leaflet from the Technical Youth Program (PDF)

The Technical Youth Program at is a free service for UCONN students, which offers:

o   Resume critiques from local recruiters

o   Technical interview preparation

o   Market insight into technical roles within companies in the Hartford, Stamford, and Boston location

Their goal is "to help students find a role after graduation, that fits their passions in the technical field".  They "partner with clients throughout the northeast, to fill their entry-level roles."
