We had a strong turnout and a nice variety of papers on many different areas of complexity with particularly strong showings in quantum complexity and structural complexity making a comeback.
Although I did not have my own talk in the conference, I presented a paper by Buhrman and Torenvliet since they unfortunately could not be in Amherst. I like giving talks on other people's work since you can be honest about the strengths of a paper without having to brag. My favorite result in their paper showed that if you take a many-one complete set for EXP, remove any easily computable set of subexponential size, what remains is Turing-complete for EXP. The proof is a clever recursive algorithm using the set itself to find safe places to map the reduction.
Next year we have our 20th conference in San Jose followed by Prague in 2006.
