Presentations

The project for the course is a short slide presentations (up to 15 minutes) on the main high level ideas in some paper or on some open problem or topic in sublinear algorithms and what is known about it. These can also be descriptions of an application/implementation of the topics or ideas in the general area of the course to work you are doing or have done. Any of the open problems or topics on the sublinear.info website would be a good choice. Some sample topics and associated papers are listed below.
