You must prepare your homework using a word processor, editor, or other software that can produce typeset results, including math. Scans or photographs of handwritten solutions are not acceptable. Also, please do not use plain text with "ASCII math" (i.e. simulated displayed formulas produced using creative spacing and underline/dash characters) or "ASCII art" in place of figures. We strongly recommend the use of LaTeX to prepare your solutions. LaTeX is the de facto standard method of typesetting published work in compter science, and it is especially well suited to typesetting mathematics. If you are unfamiliar with LaTeX, you can obtain the necessary software, including an editor here. You can use this example document to help you get started. The LaTeX Wikibook may also help as a reference that explains the various features of LaTeX in much more detail.
Please prepare each problem's solution as a separate document, since you will be uploading each solution separately to Blackboard for grading. You may put all the parts of one problem's solution (e.g. 1(a), 1(b), ...) in a single document. Each solution must have a header appearing at the top of each of its pages that includes your name and WUSTL Key ID (e.g. "jbuhler"), the homework number, and the problem number. Page numbers at the bottom of each page are optional but recommended.
Your homework should use a page size of 8.5x11 inches ("letter" size; A4 is also OK). Most text should be in a proportionally-spaced font with a size of at least 11 points. (However, you might find that a fixed-width font such as Courier is better for writing pseudocode with consistent indenting.) You should use black text on a white background everywhere except possibly in figures. Your figures may be in color if desired, but your TAs might be red-green colorblind, so choose your palette appropriately.
Figures may be drawn using the tool of your choice, or even hand-drawn and scanned as images, so long as they are legible in your final submission. Vector graphics (i.e. those stored as a set of shapes and lines) are preferred to bitmapped images such as GIF, PNG, or JPEG, but either is acceptable. The LaTeX Wikibook includes instructions on how to include these images in your document, including how to crop them. You may find the TikZ package convenient for drawing figures of graphs, as in this example. Place your figures, scaled appropriately, inline at the point where they are first referenced in your document, or use your editor's "float" facility (if any) to have them appear at the top or bottom of a page with suitable captions and corresponding references in the text. Please do not just put all figures at the end of the document.
To help you follow these formatting standards, we have created a LaTeX template as a starting point for each solution.
You can name your documents whatever you want, but I recommend that you limit the characters in your names (other than the file extension, if any) to English letters, numbers, spaces, dashes, and underscores to avoid tickling any unexpected bugs in Blackboard.
Click the folder corresponding to the homework you want to submit. You'll see an icon and link for submitting a solution to each individual problem:
Click the "Browse My Computer" button and pick the file you wish to submit. Your selection will appear under the heading "Attached files":
If you've selected the wrong file, click "Do not attach" and try again.
Do not do any of the following:
You can optionally write a note to the grader in the "Add Comments" box. This would be a great place to note any sources of help you got for the problem, consistent with the course collaboration policy.
Check carefully to make sure the document appears as you expect, then select "Continue" to return to the submission form. If you saw an error in your document, click the "Mark for removal" option next to the attached document to get rid of it, attach a corrected version, and preview again.
Note that merely uploading a document as a draft in Blackboard does not make it visible to the instructor or TAs and does not constitute turning it in. You can still upload newer versions of your document at any time after saving and before submission, using the above procedure. To save time turning in solutions at the last minute, you may wish to save your solution to each problem as a draft in Blackboard as you complete it, but wait until the due date to actually submit, in case you later decide to change a solution.
NB: if you see a blank page instead of your document in the viewing window, you forgot to upload the document before hitting "Submit." You'll have to ask the instructor or a TA to undo the submission before you can correct it.
The TAs will grade each of your homework solutions in Blackboard. As each problem's solution is graded, a grade will be posted to the corresponding column in the course grade book.
To see your graded solutions, select "My Grades" from the course's left-hand menu in Blackboard, and select "Graded" to see only graded work. For each solution, you'll see the points awarded and the time it was entered. To see the graders' comments, click on the problem name, which will take you to an online view of the marked-up document:
You can then examine the notes and comments on the document, each of which is tagged with the name of the instructor or TA who wrote it. You can download the marked-up version of the document for your records as a PDF by selecting the down-arrow icon at the upper left of the document view. If you wish to dispute the grading of a particular problem, all TAs and the instructor can see your marked-up homework in Blackboard; you don't need to print it out or send us a PDF.
We will retain your marked-up homework documents in Blackboard until the end of the semester.
