Entropy and self-organization in multi-agent systems

Emergent self-organization in multi-agent systems appears to contradict the second law of thermodynamics. This paradox has been explained in terms of a coupling between the macro level that hosts self-organization (and an apparent reduction in entropy), and the micro level (where random processes greatly increase entropy). Metaphorically, the micro level serves as an entropy “sink,” permitting overall system entropy to increase while sequestering this increase from the interactions where selforganization is desired. We make this metaphor precise by constructing a simple example of pheromone-based coordination, defining a way to measure the Shannon entropy at the macro (agent) and micro (pheromone) levels, and exhibiting an entropybased view of the coordination. Keywords Self-Organization, Pheromones, Entropy.
