In this talk, I will present work on two very different
problems, with the only common theme being a substantial departure from
standard approaches. In the first part, I will discuss how the spread of
many common contagions may be more accurately modeled with nonlocal
approaches than with the current standard of local approaches, and I will
provide a minimal mathematical foundation showing how this can be done. In
the second part, I will present a new computational method for ranking
items given only a set of pairwise preferences between them. (This is
known as the minimum feedback arc set problem in computer science.) For a
broad range of cases, this method appears to beat the current "world
record" in both run time and quality of solution.
