Bonabeau hierarchy models revisited

Dominance orders in animal societies: the self-organization hypothesis revisited.

In previous papers (Theraulaz et al., 1995; Bonabeau et al., 1996) we suggested, following Hogeweg and Hesper (1983, 1985), that the formation of dominance orders in animal societies could result from a self-organizing process involving a double reinforcement mechanism: winners reinforce their probability of winning and losers reinforce their probability of losing. This assumption, and subseque...

High level Ab inito bench mark computaions on weak interactions (H2)2 dimer revisited

The Potential Energy Surface PES of (H2)2 dimer has been investigated, using five simple rigid rotor models. These models are called: head to head, symmetric side to side, L , steplike and T model. All calculations were done at two levels of ab initio  methods: MP2(Full) and QCISD (T,Full) using cc-pVTZ basis set at singlet state of spin multiplicity. The results of scanning PES were then fitte...

The Emergence of Social Hierarchies

The Bonabeau model attempts to explain the origin of hierarchical structure in society on the basis of random aggressive interactions between agents in the society. Agents which win most of their fights rise higher in the hierarchy, while those who lose most fights occupy the lower tiers. This model grew out of ethological studies on eusocial wasps, but has been subsequently modified to represe...

The model of Bonabeau et al explains social hierarchies as random: People keep a memory of recent fights, and winners have a higher probability to win again. The question of phase transition and the generalization from square lattices to networks is reviewed here.
