The effect of laziness in chasers in group chase and escape model

TL;DR

This paper investigates how different types of laziness among chasers affect group chase and escape dynamics, revealing that strategic laziness can enhance catching efficiency through coordinated attack formations.

Contribution

It introduces a simple model to study laziness in chasers, demonstrating that division of labor-based laziness can improve group chase efficiency.

Findings

Uniform laziness is ineffective in improving catch success.

Division of labor laziness enables formation of pincer attacks.

Strategic laziness can enhance group hunting performance.

Abstract

The effect of laziness in the group chase and escape problem is studied using a simple model. The laziness is introduced as random walks in two ways: uniformly and in a "division of labor" way. It is shown that, while the former is always ineffective, the latter can improve the efficiency of catching, through the formation of pincer attack configuration by diligent and lazy chasers.
