Announcements

Tue Sep 9
  • The deadline for Homework 2 has been extended to Wed Sep 10 at 9pm due to a discrepancy on the Course Calendar page.
  • Some clarifications of homework policies:
    • The list of collaborators and other sources should be given as a separate page included after each lettered part of a homework problem (or after the whole problem if it consists of a single part). Please do so even if you have nothing cite (just say you have nothing to cite, "Sources and collaborators: $\varnothing$", etc.). Please do so even if the list is the same for each part. Doing so will greatly aid any graders focusing on individual parts. We understand this policy is somewhat different than what was asked for earlier, so we'll only start enforcing it for Homework 3.
    • If you use an LLM for any part of a problem, you must provide a complete transcript of the "conversation" starting on the same page as or the next page after the list of sources and collaborators. A URL for the transcript is sufficient if you can guarantee it will remain active through at least January 2026 (a clickable link is greatly preferred). If you don't use a URL, please use as many pages as necessarily to keep the transcript readable.
    • On that last note, the two page limit for each problem mentioned on the website is merely a (very firm) suggestion to warn you when you've gone off the rails. It is not enforced (beyond the grader giving up when there's too much to read), and it certainly does not apply to any citation list or LLM transcript.
Thu Sep 4
Homework 1 solutions are available.

  • Starting this Thursday (September 4), we will hold weekly homework parties every Thursday 6–8, Sunday 4–6, and Monday 6–8 in Siebel 0216. These are structured office hours where groups of students can work together on homework, with the guidance of course staff.
  • Reminders about the homework due tomorrow:
    • Please read the homework policies. In particular:
      • Every homework submission must include a complete list of all sources and collaborators. (You do not need to cite official course materials or sources for prerequisite material.) If your set of sources and collaborators is empty, write “Sources and collaborators: $\varnothing$”.
      • If you use an LLM for any reason, you must include the LLM in your list of sources, and you must submit a complete transcript of your prompts and responses.
    • Please read the standard grading rubrics, especially the stadnard induction rubric. This is how we will score your homework.
    • Please read the lab solutions and the solved problems in the homework. These model the structure and level of detail that we expect in your homework solutinos.
    • Exactly one member of each homework group should upload your submission and identify the other group members to Gradescope. You can submit as many revisions as you like before the deadline, but you must identify your group members every time you submit.
Sat Aug 30
  • This coming Monday September 1st is Labor Day, which is a university holiday. All office hours for that day are officially canceled.
  • Starting next week, Emily will hold her regularly scheduled office hours Wed 11-12 and Thur 4-5. Office hours for the rest of the course staff along with other events can be found on the calendar embedd in the Weekly Schedule page.
Fri Aug 29
Today's lab handout has been revised to remove an error and clarify one of the problem statements; all revisions are highlighted. Solutions for both of this week's labs are available.
Wed Aug 27
  • The course Discord server is now publicly available to those who want to read posts. Any current student of UIUC (and not just those registered for this class) can post as well after providing their netid and password through a link in the server's #rules channel.
Tue Aug 26
  • Jeff didn't have much time to do the technical portion of today's lecture, so Emily recorded another take that goes a bit slower and discusses more examples of proof by induction.
  • Emily's first office hours will be tomorrow (Wed Aug 27) from 11 to 12.
  • All office hours will be announced on Ed Discussion and Discord and posted on the Google calendar on the weekly schedule page. In particular, Jeff's first office hours will be tomorrow (Wed Aug 27) from 3 to 4.
  • If you are waiting to register for the class for any reason, please submit Guided Problem Set 1 and Homework 1 as if you are already registered. Because we need to release solutions immediately after the submission deadline, we cannot give homework extensions to students who register late.
Mon Aug 25
Guided Problem Set 1 and Homework 1 are available. Normally guided problem sets are due Monday at 9pm, and homeworks are due Tuesday at 9pm; both deadlines are delayed 24 hours this week because of Labor Day.

  • Welcome! We’re working hard to get everything set up here before the semester begins. Meanwhile, you may notice several inconsistencies, broken links, and inaccurate dates.
  • As in past semesters, there are two independent sections of CS/ECE 374. This is the web site for Section A, or more formally: lecture section AL1 and lab sections AD*. Section B, taught by Nickvash Kani and Daniel Alabi, has a separate site.
