Surveys are not acceptable. Reviews are discouraged unless they contain significant original critical content. You are welcome to, encouraged to, but not required to use computational tools in your work. It is acceptable if you are unable to solve your original problem. In this case, document your findings and partial work, and try to solve a simple special case of your problem.
Most successful work is highly focused.
Pick a thesis that interests you greatly. Format Requirements You must communicate your findings in the form of a written technical report. There is no page limit. I suggest about 10 pages. Less than five leaves little room to develop an idea, and I don't want to read much more than 10 pages unless the report is extremely good.
