My name is Hendrik Schawe. This site is about the achievements of
my short academic career.
I am fascinated by simple models exhibiting an unexpected depth.
Examples, which I studied, are the easily defined
traveling salesperson problem turning out to be very hard to
solve; the complex behavior and surprising properties of simple
models, like the self-avoiding random walks following fractal paths or
longest increasing subsequences showing surprising connections
to random matrix theory and KPZ growth processes. Also
phase transitions arising from simple interaction rules spark my
interest, like in the Ising model for ferromagnetism
or the Hegselmann-Krause model for bounded-confidence
opinion dynamics.
Since simulations are my main tool, I am interested in algorithms
enabling the study of problems which are on the first glance
infeasible, like directly sampling the large deviation
regime of an observable with Markov chain Monte Carlo methods, finding
exact solutions of moderately sized traveling salesperson instances
using linear programming or just pushing the envelope of the system
sizes which can be simulated.
