Meeting Strangers and Friends of Friends: How Random are Social Networks?
We present a dynamic model of network formation where nodes find other nodes with whom to form links in two ways: some are found uniformly at random, while others are found by searching locally through the current structure of the network (e.g., meeting friends of friends). This combination of meeting processes results in a spectrum of features exhibited by large social networks, including the ...
متن کاملA fast algorithm for identifying Friends-of-Friends halos
We describe a simple and fast algorithm for identifying friends-of-friends clusters and prove its correctness. The algorithm avoids unnecessary expensive neighbor queries, uses minimal memory overhead, and rejects slowdown in high over-density regions. We define our algorithm formally based on pair enumeration, a problem that has been heavily studied in fast 2-point correlation codes and our re...
متن کاملRanking Friends ∗
We investigate the scope for cooperation within a community engaged in repeated reciprocal interactions. Players seek the help of others and approach them sequentially according to some fixed order, that is, a ranking profile. We study the ranking profiles that correspond to the social structures that are most effective in sustaining cooperation in equilibrium, that is, social structures that s...
متن کاملScalar Glueballs and Friends
The f0(1500) is identified in three glueball favoured production mechanisms: pp̄ annihilation, ψ → γf0 and Central Production. The production rate for glueballs in ψ → γG has been quantified and the f0(1500) is found to be consistent with a glueball qq̄ mixture. We illustrate a remarkable property of central production where kinematic cuts appear to make a systematic separation between glueballs ...
