Motivation and Approach

The collective behaviour of individuals is widely observed in many natural and social systems. In these systems, Newton’s third law, or the law of action–reaction, is often violated. Hence, interaction between individuals is often non-reciprocal. In this study, as the first step towards elucidating the essential mechanism of the aforementioned systems, a minimal model of collective behaviour based on non-reciprocal interactions is proposed by drawing inspiration from friendship formation in human society.
