3.2 The Community

The basic cycle for the community of MOVERS-WORLD goes as follows:

1.
A problem is generated for the community of actors to solve.
2.
The community of actors solves the problem.
3.
Offline learning occurs.

The overall control structure for the community of MOVERS-WORLD is not hierarchical nor is planning centralized [25]. In other words, actors do not share an overarching plan [17] or reason explicitly about group concepts [72], rather cooperation emerges from local interactions. The capacities of other actors is not treated as a given, but this information is acquired through experience.

Improvement in the performance of the community occurs over several generations of problems -- as a result of practice. During step 2, individuals are satisfied with any solution. In step 3 the actors store into memory the portions of the behavior that were essential to the solution. In future episodes, segments of the behavior are recalled and further improvements can occur. Thus, regularities in the coordination of behavior in joint activities develop over time and the behavior of the community will evolve and improve.

In MOVERS-WORLD, the memory of the community of actors is distributed: individuals have access to only their private memories of their experiences and there is no offline discussion to form a consensus on the best way to accomplish their joint goals. At issue will be the processes by which actors within the community, with sometimes overlapping and sometimes conflicting experiences, converge on conventions for coordinating joint behavior for regularly occurring problem situations in the domain of activity.
