• Generic vector-agents 

    Hammam, Yasser; Moore, Antoni; Whigham, Peter A; Freeman, Claire
    The work reported here has been motivated by the need for a generic spatial model to overcome the limitations of Cellular Automata (CA) regarding the rigid square-cell structure and limited neighbourhood configurations. A ...
  • Irregular vector-agent based simulation for land-use modelling 

    Hammam, Yasser; Moore, Antoni; Whigham, Peter A; Freeman, Claire
    Urban structures exhibit complex patterns made of heterogeneous and irregular objects. Few works in the computational urban modelling literature have considered and examined the real geometric boundary of the city’s objects. ...
  • The storage and reconstruction of polygon boundaries using circles 

    Moore, Antoni; Mason, Chris; Whigham, Peter A; Thompson-Fawcett, Michelle
    This paper investigates the accuracy of using circles to store polygon boundaries. Can a series of xy points be accurately replaced by a smaller array of variably-sized circles used in a non space filling sense to approximate ...
  • A vector-agent paradigm for dynamic urban modelling 

    Hammam, Yasser; Moore, Antoni; Whigham, Peter A; Freeman, Claire
    In the past, researchers and model developers were restricted by their theoretical knowledge about the city and how it might be simulated as well as constrained by technological limitations. Nevertheless, the simulation ...
