The basic idea is to develop a method to search for valid parameter sets of ABSs through intensive simulation experiments. In this case study, we focus upon the diffusion process of the agriculture and pottery in the Gusuku period (eleventh–fourteenth centuries) in Okinawa, Japan. Following our intensive simulation results, we propose plausible but falsifiable hypotheses: (1) agriculture spread rapidly among native people and was, in the early stages, performed mainly by native people; and (2) the immigrant-style pottery was mostly used by immigrants and was not widely diffused among native people. These hypotheses should be verified by the new discovery of anthropological and archeological evidence. Therefore, these ABSs will contribute to the literature in the fields of anthropology and archeology in Japan. Keywords: anthropology, archeology, hypothesis generation 67 doi: 10.18278/jpcs.2.2.5
