Echo: Model of agent interactions

Echo is a model of complex adaptive systems proposed by John Holland, in which virtually all of the physical details of real systems have been abstracted away. Instead, it concentrates on a small set of primitive agent-agent and agent-environment interactions. The goal of Echo is to study how simple interactions among simple agents lead to emergent high-level complex phenomena such as the flow of resources in a system or cooperation and competition in networks of agents (e.g., communities, trading networks, or arms races). See the readme.txt file and the file for an extended description.
