Announcements:

  1. Final Grades instructor will be available by appointment to discuss grades, hand back previous work, and show you your final (the exams themselves must be kept for another semester). Solutions to the final will be posted at some point, for those interested.
  2. corrections to the lisp part of programming assignment 5: there was an error on the printing function so that it printed the ne and nw kids in reverse order. They have been corrected on the quad.lisp file. (2pts dt15). Also, search and remove are builtin lisp functions, so use qt-search and qt-remove, instead (2pts dt61).
  3. Final exam times set (may 15th):
  4. Make-up programming assignment will be to complete and redo the original quadtree project. For make-up points on lisp assignments, you'll have to do lisp varients of the quadtree functions. See the assignment below.
  5. Partial cumulative grades added to Grades page
  6. 3/11: new grading policy: The first person to point out a mistake in an assignment gets 2 points. Thus you're encouraged to read and notice these early. This applies only to actual errors, though clarifications are also appreciated.
  7. come see the instructor to claim old homeworks you haven't picked up.
  8. 3/3 Added actual lisp code for functions discussed in class, to supplement the class overheads. Selected answers to written assignment 2 also provided.
  9. 2/25 Added link to a new page of hints from the TA.
