When Woody Harrelson escapes the living dead in “Zombieland,” a new movie opening this Friday, should he head for the hills or the mall? A recently published research paper suggests that he’s probably better off hiding in the mall to save his delicious brain.

The world is full of things that move in zombie-like fashion, such as particles flowing through a turbulent fluid or the unpredictable price changes of the stock market, so physicists seek insight into this behavior by creating so called “random walking” models.

Physicist Davide Cassi at the Università di Parma in Italy looked at how long an entity hiding in a complex structure could survive if being pursued by predatory random walkers. Cassi’s paper, recently published in the journal Physical Review E, is the first to describe a general principle of a prey’s likelihood to survive over time while hiding in an irregular structure.
