To establish a system following Pareto’s principle(for example Ant society), the system must satisfy the following three cases. In our model, all nodes have the same genetic circuits and take two states, A (worker) and B (idler), depending on the surrounding circumstances.

Condition 1. Bistable state

The system is stable containing nodes A and B at certain ratio.

Condition 2. Unstable state with node A removed

By removal of node A, the system containing only node B becomes unstable.

Condition 3. From unstable to stable state

In the unstable state, some node B become A while the others remain B. The system then becomes stable again.
