This is remarks for grading the project:

Hodges

Apparently you implemented <= instead of >=. This should not be a problem, however the satisfiable tests fail. It appears that you implemented the correct procedure (SAT for Addition constraints not just difference constraints) and other than the above it look good. I would like to see you about a possible better grade. If you can show me that you can modify my tests to pass, I'll give you a 20/20.

Recommend: 18

Augustyn

Implemented the book sat method which only does difference constraints.

Recommend: 17

Yue

You only implemented difference constraints. But a very nice program interface!
