Stigmergy is a method of indirect communication which is based on modifying local environment. The term is used in multi-agent systems and communication in computer networks.

The action taken by one agent may affect the outcome of the actions of another agent without direct interaction between them. This influence may be thought as passive or active stigmergy. The first kind occurs when agent alters its environment so as to affect the sensory input of another agent. The second occurs when an agent's action alters its environment such that the environmental changes made by a another agent are also modified. Stigmergy allows simple systems to produce a wide range of apparently highly organized and coordinated behaviours and behavioral outcomes, simply by exploiting the influence of environment.
