Errata for HW solutions

Two mistakes have been brought to my attention in the HW1 solutions: Section 1.1, Question 7(e) should read "The food is good OR the service is excellent" and Section 1.1, Question 26 should read "(A OR B) AND NOT(A AND B) AND NOT C"

Homework solutions posted

To help you prepare for the exam, the homework solutions for HW1 and HW2 have been posted on the monthly schedule (under the entry for their respective due dates). I have also prepared the solutions for HW3 and will post them after lecture on Friday.

Former Section B Students: Make Sure You Are Registered

If you had originally registered for section B of CSE 191 and your records do not indicate that you are registered for CSE 191 anymore (please check this on MyUB), then you should send email to Jaynee Straw (straw@cse.buffalo.edu) including your name, your person number, and the registration number for one of the section A recitations.

Start on HW1

Generally I will formally announce each homework the Friday before it is due, but feel free to start forming groups (remember you can and should work together!) and look at the problems from HW1. After lecture on Friday (8/31) you will have everything you need to solve these problems, but feel free to read the book for this info as well.

A Note about Instructors

I (Adrienne Decker) am the official instructor for this course. However, I am currently home enjoying my new baby. I will be back on October 1. In my absence, Albert Goldfain has been assigned to act as instructor in my place. During my absence, all correspondence about course issues should be directed to him. Decisions on the grading of coursework and exams has (when possible) been done in consultation with me. Therefore, his word on grading issues is final in my absence as well.
