{"intvolume":"       108","abstract":[{"lang":"eng","text":"We introduce a stochastic cellular automaton as a model for culture and border formation. The model can be conceptualized as a game where the expansion rate of cultures is quantified in terms of their area and perimeter in such a way that approximately geometrically round cultures get a competitive advantage. We first analyze the model with periodic boundary conditions, where we study how the model can end up in a fixed state, i.e., freezes. Then we implement the model on the European geography with mountains and rivers. We see how the model reproduces some qualitative features of European culture formation, namely, that rivers and mountains are more frequently borders between cultures, mountainous regions tend to have higher cultural diversity, and the central European plain has less clear cultural borders."}],"article_processing_charge":"No","status":"public","publication_status":"published","date_published":"2023-11-08T00:00:00Z","publisher":"American Physical Society","type":"journal_article","language":[{"iso":"eng"}],"related_material":{"record":[{"status":"public","relation":"research_data","id":"12869"}],"link":[{"url":"https://github.com/FrederikRavnKlausen/model-for-culture-formation","relation":"software"}]},"oa_version":"Preprint","date_created":"2023-05-04T08:35:01Z","issue":"5","title":"Stochastic cellular automaton model of culture formation","month":"11","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","external_id":{"arxiv":["2305.02153"]},"publication":"Physical Review E","author":[{"first_name":"Frederik Ravn","full_name":"Klausen, Frederik Ravn","last_name":"Klausen"},{"first_name":"Asbjørn Bækgaard","orcid":"0000-0003-4476-2288","last_name":"Lauritsen","full_name":"Lauritsen, Asbjørn Bækgaard","id":"e1a2682f-dc8d-11ea-abe3-81da9ac728f1"}],"scopus_import":"1","article_number":"054307","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2305.02153","open_access":"1"}],"_id":"12890","year":"2023","article_type":"original","publication_identifier":{"issn":["2470-0045"],"eissn":["2470-0053"]},"oa":1,"volume":108,"department":[{"_id":"GradSch"},{"_id":"RoSe"}],"date_updated":"2023-11-13T07:47:30Z","doi":"10.1103/PhysRevE.108.054307","acknowledgement":"Thanks to Kim Sneppen, Svend Krøjer, Peter Wildemann, Peter Rasmussen and Kent Bækgaard Lauritsen for discussions and suggestions.
