NUMB3RS - Season 3 - "End of Watch" - Ants Go Marching

Published on 10/17/2008

Activity Overview

In "End of Watch," Charlie claims that the gang member accused of murdering a police officer is probably innocent. He bases this on the likelihood that there was no way for the gang member to find a single safe path between rival gang turfs. He refers to 'Collective Behavior Theory' for a mathematical model known as 'Ant Colony Optimization' (ACO) to demonstrate this.
Students will use directed graphs to simulate an ACO.
