Modelling the flight of starlings By Simon Byford ‐ sjb17u@cs.nott.ac.uk Supervised by Dr. Jason Atkin ‐ jaa@cs.nott.ac.uk School of Computer Science University of Nottingham Submitted May 2011, in partial fulfilment of the conditions of the award of the degree: BSc (Hons) Mathematics and Computer Science I hereby declare that this dissertation is all my own work, except as indicated in the text Signature: May 6th, 2011 Abstract A project was undertaken to build a software model capable of accurately simulating the flocking behaviour of starlings. After reviewing the relevant literature and studying the mechanics of flocking, such a model was carefully designed and implemented in the Java programming language. The model is capable of exhibiting a range of flocking behaviours with simulations comprising upwards of 200 individual birds. A great number of behavioural parameters are available to edit before and during simulations, where their effects can be viewed in real time. The ability to spawn virtual falcons as well as starlings introduces the notion of a predator which is an area largely unexplored in previous models. A number of interesting observations were made during the analysis phase of this project, including the fact that simulations employing metric and topological distances induce much the same flocking behaviour, and that the application can typically handle simulations comprising up to 500 individual birds before experiencing significant drops in performance. In summary, the project was deemed highly successful and a number of possible future extensions were proposed. 1 Table of contents Abstract

In the first half of the game the Falcons took nine shots on goal but it wasn't until the middle of the first half that the Falcons were able to find the back of the net.
