ISyE 6662 - Spring 2013: Homework guidelines

The solutions to the homework are required to be typesetted in LaTeX. Please find a LaTeX template and more information in the LaTeX folder in the Resources section of the course's T-square site.

Please follow the following guidelines regarding your homework solutions:

Homeworks are meant as individual assignments. Although you are encouraged to discuss them with your classmates, each student should complete and submit his/her own work, unless specifically instructed to work in groups. Cite all reference sources used in your assignments. Late homework submissions will not be accepted, except for serious unavoidable circumstances.

Write your name and class clearly at the top of at least the first page, along with the assignment number and the page number(s). If you are not stapling or paper-clipping the pages together, then put your name or initials on all the pages.

Citing Marcus Smith (maintainer of pip):

If you think the global site is out of date, and want the latest in the user site, then use:

pip install --upgrade --user SomePackage

If the global site is up to date, and you really just want the same thing duplicated in --user, then use:

pip install --ignore-installed --user SomePackage

Best of read.write.as

read.write.as is a kind of a blogging service but in which most of the posts are anonymous. This gets people to write very deep stuff. It's hard not to start imagining the person on the other side.
Here are some of my favorite posts:

• Hi
• Have you ever wondered how different life would be if you had just changed one decision?
• oral worship and you
• “We have so much in common!”
