    "abstract": "Boolean networks may be viewed as idealizations of biological genetic\nnetworks, where each node is represented by an on-off switch which is a\nfunction of the binary output from some other nodes. We evolve connectivity in\na single Boolean network, and demonstrate how the sole requirement of\nsequential matching of attractors may open for an evolution that exhibits\npunctuated equilibrium.",
