Assignments

  • Assignments generally are given out Thursday and are due the following Thursday, but the schedule may vary.
  • Unless otherwise noted, assignments are individual assignments. They must represent your own work. You may consult any public resources such as papers, reports, or lecture notes, but you must explicitly credit such external resources in your answers. You are not permitted to draw upon assignments or solutions from previous instances of this course or other courses in preparing your work. Carnegie Mellon's policy on academic integrity applies to this course.
  • Some problems may be explicitly annotated as allowing collaboration, with a problem-specific policy spelled out.
  • Homeworks may require small implementations, or write-ups with LaTeX or with pencil and paper and scanned as a (legible!) PDF.
  • If you want to typeset your answers, some sample LaTeX lecture notes and necessary style file are included in the handout source hwNN.zip file.
  • Emphasis is on correctness and elegance. Some assignments may be difficult. If you cannot do them, write down your thoughts, but never hand back an incorrect "proof".
  • Written homeworks are due at 11:59pm on the due date.
  • Homework may be handed in late without penalty if the instructor is notified in advance. See Assignment Due Dates.
  • Assigments should be submitted as PDFs via Gradescope or as Lambda source file, as specified in each assignment.
  • We will try our best to return graded homework before lecture the week following after the due date.
