The principles of the EVS approach are the modeling of multi-agent systems with 1) a diversity of agents, 2) non-locality of connections between them and 3) resource flow through the agent and through the system. Four main models were developed within the EVS approach. The connection structure of these models was studied as a function of two main parameters: sociability (the maximum number of connections which an agent can hold active at a given time step) and compatibility (a measure of the effectiveness of a connection in a population of diverse agents). Variations in these parameter values resulted in the appearance of stochastic phase transitions. The models illustrate the effect of group dynamics on individual behavior.
