J. Holland explains here "emergence": how patterns persist in complex adaptive systems (CAS). He starts with a general discussion about models, follows with a model of the checker board game, and gradually introduces neural networks. He then presents generative constraint procedures (GCP), a way to describe these CAS, which while being formal, remain accessible—at least I followed. After a discussion reductionism, he concludes with the current status and future of research on the topic.
I find this book much broader than Hidden Order: How Adaptation Builds Complexity. I found the presentation of the checker game and of the neural network very clear, and yet deep. I also appreciate the very nuanced discussion about reduction and levels. I think this a very good reference on CAS: I found this text much more accessible than others such as Complex Adaptive Systems: An Introduction to Computational Models of Social Life for instance. I recommend it, definitely.
