You are to implement/prove/create/improve some portion of the work involved with your project. This can be very open, but should be discussed with the instructor. It should demonstrate an understanding of some reasonably new aspect of the topic you are investigating. The implementation should be sufficiently accomplished to be presentable, in some form.
A implementation proposal is due with your project proposal on September 21st. This should be a several paragraph write up of what you intend to implement.
Submission of your final project depends on what was done and should be discussed with the instructor.
