Quantification of group chasing and escaping process

TL;DR

This paper introduces a model for group chase and escape behaviors, classifying configurations into patterns and quantifying movements to understand hunting efficiency.

Contribution

It presents a new parameter-based classification system for group chase and escape configurations, including formations like one-directional and surrounded patterns.

Findings

Identifies key configurations like one-directional and surrounded formations.

Quantifies pincer movements and aggregation processes.

Highlights how configurations affect hunting efficiency.

Abstract

We study a simple group chase and escape model by introducing new parameters with which configurations of chasing and escaping in groups are classified into three characteristic patterns. In particular, the parameters distinguish two essential configurations: a one-directional formation of chasers and escapees, and an escapee surrounded by chasers. In addition, pincer movements and aggregating processes of chasers and escapees are also quantified. Appearance of these configurations highlights efficiency of hunting during chasing and escaping.
