    Infusing Virtual Creatures with Vision
    (2008-06-16T21:04:01Z) Jacob, Christian; Pilat, Marcin L.
    In this paper, we evolve light following behaviours in preevolved virtual creatures. The neural controllers of creatures evolved for movement are augmented with simple visual neurons and neural connections. The resulting neural networks are trained for light following by an evolutionary algorithm. We show that, through this process, we are able to train the neural controllers to follow a light source. Many of the evolved behaviours show stability and adaptiveness to environmental perturbations of body orientation.

    Simplified models of Dictyostelium discoideum aggregation and slug migration
    (2006-11-15) Pilat, Marcin L.
    Biological models of Dictyostelium discoideum behaviours are often quite complex. Computer simulations using simplified models provide insight into the biological behaviours but rely on complex mathematics. We studied whether characteristic slime mold behaviours can occur in very simple models that can be easily implemented with any graphical simulation engine. We proposed two excitation based models: neighbour and spherical models, and one simplified cAMP propagation model - the grid model. We succeeded in producing streaming and spiral patterns in aggregation and characteristic thermotaxis in the slug migration life stage of Dictyostelium discoideum.

    Wasp-Inspired Construction Algorithms
    (2006-11-15) Pilat, Marcin L.
    In this paper, we present our research into wasp-inspired construction algorithms. We were able to implement a typical construction algorithm in a 3D simulation environment and reproduce the results of previous research in the area. Finally, we present case studies that consider the impact of rule changes on the resulting evolved architectures.
