I'm writing REU applications and have a question relating choosing REUs to apply to. I want learn more about individual REUs, but can't find very specific information except for some REUs that post papers relating to the projects (not done often). While this is useful for looking at the subject matter of the projects, a lot of programs seem pretty similar in that they mostly focus on combinatorics/discrete math and I don't know what makes one program particularly different from another. Also, I'm not sure about where to find more specific things like how the programs are structured and so on. Does anyone have suggestions for how to find things like this?
