Motifs in evolving cooperative networks look like protein structure networks
A motif analysis of networks produced by peer-to-peer protocols that support cooperation between evolving nodes is presented, and is surprised to find that their motif profiles match closely protein structure networks.
SLACER: a self-organizing protocol for coordination in peer-to-peer networks
SLACER is a selfish link-based adaptation for cooperation excluding rewiring that self-organizes the network into a robust artificial social network (ASN) with small-world characteristics and high cooperation.
Greedy Cheating Liars and the Fools Who Believe Them
It is observed that in the first case, a certain percentage of such "greedy cheating liars" can actually improve certain performance measures, and in the second case, the network can maintain reasonable levels of cooperation even in the presence of a limited number of nihilist nodes.

An algorithm is proposed, called SLACER, that allows peer nodes to create their own friendship networks, through randomized interactions, producing an artificial social network (ASN) where nodes share high trust with their neighbors.

An algorithm (SLACER) is proposed that allows peer nodes to create and manage their own friendship networks and could supply ASN to P2P applications that currently depend on human social networks thus transforming them into fully autonomous, self-managing systems.

It is found that the evolving network functions to select and spread more optimal equilibria while resisting invasion by lower ones, so the network acts as a kind of “social ratchet” selecting for increasing social benefit.

The results demonstrate that SLAC augmented with NEWSCAST produces high levels of cooperation, which increases confidence that previous results from SLAC are generally applicable and valid and also thatSLAC could have applications in real implemented systems.
Towards a Group Selection Design Pattern
A general mechanism based on an evolutionary “group selection” process in which individual entities dynamically copy the behavior of other entities if they achieve higher performance is proposed.
If multiple slots occur in a row, then the extra minimum space and propagation delay costs must be amortized over these slots.
Broadcasting at the Critical Threshold in Peer-to-Peer Networks 1
A modified flood-fill algorithm is presented that increases efficiency and reduces the incentive for freeriding while retaining the robustness and simplicity of the original scheme and makes use of an evolutionary approach in which nodes copy strategies of others.
