The Collective Behaviour Group at the Faculty of Computer and Information Science, University of Ljubljana which is led by Associate Professor Iztok Lebar Bajec and is based within the Laboratory of Computer Structures and Systems. Our work is focused on using soft computing methods to model coordinated behaviour in biological systems. Animal groups such as fish schools, insect swarms and bird flocks are frequently admired in awe as they exhibit complex coordinated behaviour. May these behaviours result from social interactions among individuals or be fruit of our pattern seeking minds we are researching soft computing algorithms that allow controlled entities to display behaviours similar to those observed in nature. Our aim is to support Biologists in forming or proving their hypotheses about why and/or how animal groups behave as they do. Our group, under the premise that most of the existing knowledge about the behaviour of bird flocks is available in the form of descriptions and explanations of the perceived behaviour collected by field ornithologists, developed a fuzzy logic based computer model of bird flocking which uses fuzzy logic to describe an individual’s drives. Simulations performed using our model present behaviour remarkably similar to behaviours of natural flocks. Our current research activities are concentrated on the extension of the model to support studies of various collective behaviours, such as: landing and takeoff studies, sensory system studies, predator/prey relations, and flocking behaviour under predation studies.
