The Neolithic revolution was one of the most influential events in human history, but why and how it occurred are still not fully understood. To try to infer what may have happened, mathematical models have been developed. We describe and implement a method of parameter space exploration when ideal outcomes of a model are known. This method is applied to a published agent-based model for the Neolithic transition, revealing previously unidentified parameter interactions, sensitivities, and complexities. Our results highlight the importance of group structuring, group size, conservatism, and farming-friendly property rights, for the switch to farming around 12,000 years ago. We also find that, although advantageous, it is not essential that farming productivity is greater than foraging productivity.
