Here's an interesting paper, by Alexander Franks, a very talented young man who was a finalist in a national competition. He explores, through the use of genetic algorithms and small world connections, how dispersed networks generate a coordinated rule set in noisy environments.
This is an interesting topic since it is not at all obvious how open source networks develop cohesive rules sets -- this in contrast to hierarchical systems that can propagate rules through central direction. In sum, his work suggests that one or two widely held rules (greater than 50% adoption) provide the basis for the evolution of an entire set. All rules that have affinity to those founding rules evolve until they are widely adopted. All minority rules that do not have much affinity are flushed. This has interesting applicability to open source warfare.It suggests that the plausible promise (the idea that starts the open source warfare community) provides a center of gravity that attracts rules that advance it and repels those that don't. Any additional work on this topic is welcome.
