Due on paper in class, Wednesday 11 May 2005, or to the CMPSCI main office by 4:00 p.m. that day

Problem 9.8.5 removed 10 May 2005.

There are nine questions for 90 total points. All are from the textbook, A Mathematical Foundation for Computer Science, from the brown volume. "Problem 1.1.2", for example, refers to Problem #2 in Section 1.1, and similarly. The number after each problem is its point value. Make sure you don't do an Exercise when a Problem is assigned!

Students are responsible for understanding and following the academic honesty policies indicated on this page.

• Page 9-34: Problems 9.6.1 (10), 9.6.2 (10), and 9.6.4 (10)

• Page 9-43: Problem 9.7.5 (10) (Note that when this construction is applied to an ordinary NFA, it usually creates a λ-NFA.)

• Page 9-50: Problems 9.8.1 (10) (Problem 9.8.5 was assigned, but is withdrawn because I haven't given you the tools to do it such as an NFA class.)

• Page 9-60: Problems 9.10.4 (10) and 9.10.5 (10)

• Pages 10-10 and 10-11: Problem 10.1.5 (10)
