On the Fitness Landscape in the $N K$ Model

Wei-Kuo Chen, Si Tang

The $N K$ model, introduced by Kauffman, Levin, and Weinberger, is a random field used to describe the fitness landscape of certain species with $N$ genetic loci, each interacting w…

On the time constant of high dimensional first passage percolation, revisited

Antonio Auffinger, Si Tang

In [2], it was claimed that the time constant $I^¼_{d} (e_{1})$ for the first-passage percolation model on $Z^{d}$ is $I^¼_{d} (e_{1}) \sim lo g d / (2 a d)$ as $d \to \infty$ , if t…
