Evolutionary computation scientists find social norms required for the transition to cooperative societies

A research team led by Hitoshi Yamamoto from Rissho University clarifies what role the diversity of social norms can play in the process of evolving cooperation by means of evolutionary computation methods. The team unveiled social norms that are required in the transition from non-cooperative to cooperative societies, yet are not needed in the maintenance of cooperative societies. The study was carried out by collaborating with colleagues Isamu Okada (Soka University), Satoshi Uchida (RINRI Institute), and Tatsuya Sasaki (University of Vienna). The results of the study were published in Scientific Reports.

“Summary of the article for general readers: A norm knockout method on indirect reciprocity to reveal indispensable norms” の続きを読む

The recent results of our study on indirect reciprocity were published in in Scientific Reports in March of 2017, titled “A norm knockout method on indirect reciprocity to reveal indispensable norms”.

Hitoshi Yamamoto gives his talk “影の英雄 ―協力の進化を支える規範―” in 63th Conference of Japanese Association for Mathematical Sociology at Kansai University on 15th of March, 2017.

Isamu Okada gives his talk “Staying norm and private monitoring in indirect reciprocity” in Game Theory Workshop 2017 at The University of Electro-Communications (UEC) on 4th of March, 2017.
