St. KAUFFMAN distinguishes as follows minimal and structural perturbations in networks:
- “A minimal perturbation is a transient flipping of a binary element to its opposite state of activity. If such a change does not move a network outside its original basin of attraction, the network will eventually return to its original state cycle”.
- “A structural perturbation is a permanent mutation in the connections or in the Boolean functions of a network. Such perturbations would include exchanging the inputs of two elements or switching an element's OR function to an Template:Ency entity function” (1991, p.66).
