Polarity, group velocity, and inter-individual spacing are characteristics of fish schools that
strongly affect individual school members. However, these characteristics are group-level …

Fish schools and other animal aggregations are often highly coupled to “emergent
properties” such as polarity, edges, and distinct shape. However, the relationship between …

The emergence of collective strategies in a prey-predator system is studied. We use the term
“collective” in the sense of the collective motion of defense or attack often found in behaviors …

We explored the factors that contribute to fish school formation and maintenance using a
series of computer simulation experiments. The factors we examined were mostly social …

This paper examines the mechanisms by which a predator selects an individual target from
a group of prey. In a predatory situation, both the group of prey and the predator move …

Many studies on swarm intelligent systems have been presented. However, analytical
treatment on swarm intelligence has not been performed sufficiently, because of difficulties …

Mathematical treatment of attention dynamics of a predator chasing prey is studied. In our
model, prey and a predator move around a two-dimensional surface. Real numbers that …

This paper deals with the problem of circle formation by multiple autonomous robots on
emergent approach. The robots in question are simple, having fan-shaped local vision …

A fish school is considered as a typical example of autonomous decentralized system
existing in nature, because it often shows a high degree of cooperation in the absence of a …

This paper deals with the effects of robot population density on the emergence of circle
formation in multiple robots system. Individual robot has a specific range of signal …
