Uncovering the overlapping community structure of complex networks in nature and society (2005)
Palla, Gergely, Derenyi, Imre, Farkas, Illes, Vicsek, Tamas
Many complex systems in nature and society can be described in terms of networks capturing the intricate web of connections among the units they are made of. A key question is how to interpret the...
Reverse engineering of linking preferences from network restructuring (2004)
Palla, Gergely, Farkas, Illes, Derenyi, Imre, Barabasi, Albert-Laszlo, Vicsek, Tamas
We provide a method to deduce the preferences governing the restructuring dynamics of a network from the observed rewiring of the edges. Our approach is applicable for systems in which the...
Statistical mechanics of topological phase transitions in networks (2003)
Palla, Gergely, Derenyi, Imre, Farkas, Illes, Vicsek, Tamas
We provide a phenomenological theory for topological transitions in restructuring networks. In this statistical mechanical approach energy is assigned to the different network topologies and...
Topological phase transitions of random networks (2003)
Derenyi, Imre, Farkas, Illes, Palla, Gergely, Vicsek, Tamas
To provide a phenomenological theory for the various interesting transitions in restructuring networks we employ a statistical mechanical approach with detailed balance satisfied for the transitions...
Simulation software for 'Simulating Dynamical Features of Escape Panic' (2003)
Helbing, Dirk, Farkas, Illes, Vicsek, Tamas
Simulation software used to produce results in cond-mat/0009448 -- published as Helbing et.al, Simulating Dynamical Features of Escape Panic, Nature 407, 487-490 (2000) -- has been made available via...
Crowd behaves as excitable media during Mexican wave (2002)
Farkas, Illes, Helbing, Dirk, Vicsek, Tamas
Mexican wave, or La Ola, first widely broadcasted during the 1986 World Cup held in Mexico, is a human wave moving along the stands of stadiums as one section of spectators stands up, arms lifting,...
Simulating Dynamical Features of Escape Panic (2000)
Helbing, Dirk, Farkas, Illes, Vicsek, Tamas
One of the most disastrous forms of collective human behaviour is the kind of crowd stampede induced by panic, often leading to fatalities as people are crushed or trampled. Sometimes this behaviour...
Freezing by Heating in a Driven Mesoscopic System (1999)
Helbing, Dirk, Farkas, Illes, Vicsek, Tamas
We investigate a simple model corresponding to particles driven in opposite directions and interacting via a repulsive potential. The particles move off-lattice on a periodic strip and are subject to...
