Abstract

In nature moving animals form group of different shapes and structures, e.g., school of fishes, flock of sheep, swarm of insects, migrating birds, even a collection of people can also exhibit various patterns. In this thesis we have studied how a group of preys chased by a predator interact among themselves and form a strategy to escape from the predator by forming various patterns. Depending upon their radius of interaction, preys might form a ring around the predator or split into different sub-groups to confuse the predator. We have also studied in details how the heterogeneity in the population helps the preys to escape even from a stronger predator.
