Midterm Exam
Wednesday
October 16th, in-class from 8am-8:50am. Solutions.
·
Material
covered: Lectures 1-16.
·
Last year’s CPSC 421 midterm
·
Practice 3, Solutions 3.
We did not discuss ambiguous grammars or non-context-free languages.
·
Practice 4.
We did not discuss non-context-free languages.
·
Practice
5. We did not discuss equivalence relations on DFA states.
Final Exam
Thursday
December 12th, 8:30-11:00am in DMP 110
·
Material
covered: Much more emphasis on the material after the midterm;
little emphasis on automata. But, no
quantum stuff on final.
·
Last year’s CPSC 421 final.
Solutions.
o
Not covered this year: Question 1.3, 1.8, 2(c), 5.
o
Solution 1b is wrong.
o
Question 10 is not relevant. We did not define
“strongly NP-complete”.
o
Unlike our final, this one has no questions at all
about NP.
o
Question 1-3: We did not discuss the Myhill-Nerode theorem.
o
Question 7: We did not discuss Subset-Sum (but it is
in the textbook Section 7.5).
