Mean cover time of one-dimensional persistent random walks

Marie Chupeau, Olivier Benichou, Raphael Voituriez

Résumé

The cover time is defined as the time needed for a random walker to visit every site of a confined domain. Here, we focus on persistent random walks, which provide a minimal model of random walks with short-range memory. We derive the exact expression of the mean cover time of a one-dimensional lattice by such a persistent random walk, both for periodic and reflecting boundary conditions.
