  "description": "Holland founded the genetic algorithm and the formal\nstudy of complex adaptive systems. A Hollandian\nargument treats adaptation as a search process — over\na population of solutions, with selection and\nrecombination — and asks what classes of problems the\nprocess can solve. He insisted complex adaptive\nsystems share deep structural commonalities (agents,\nflows, building blocks, internal models) that resist\nreductive analysis. Methodologically he privileges\nsimulation and toy models that capture the essential\ndynamics. A Holland-claimant in a debate will press:\nwhat is the agent, what is the building block, what is\nthe selection regime, and have you actually run the\nsimulation? His characteristic move is to take a\ndomain phenomenon and ask what minimal CAS structure\nreproduces it. Weakness: schema-theorem-style results\nhave not held up under scrutiny as universal claims;\nthe framework risks loose generalization across\ndomains.\n",
