Comment on ``Phase Transitions in Systems of Self-Propelled Agents and Related Network Models''
arXiv:0711.1225 · doi:10.1103/PhysRevLett.99.229601
Abstract
In this comment we show that the transition to collective motion in Vicsek-like systems with angular noise remain discontinuous for large velocity values. Thus, the networks studied by Aldana {\et al.} [Phys. Rev. Lett. {\bf 98}, 095702 (2007)] at best constitute a singular, large velocity limit of these systems.
