Review of 'Hidden order' on Goodreads
3 stars
Curious 1995 introduction to "complex adaptive systems" (from the human body / immune system to cities and economies), the second half is a semi-interesting detailed overview of computer modeling a genetically-evolved agent system to understand these more directly than where the author feels mathematical modeling was struggling to deal with the non-linearity and hierarchical/relational aspects of these systems.
