    The Engineering Applications of Artificial Intelligence (EAAI) is a journal of very high repute in the domain of Engineering and Computer Science. This paper gives a broad view of the publications in EAAI from 1988–2018, ...
  • Evaluating usage control deterrents 
    Padayachee, Keshnee; Eloff, Jan H.P. (Computer Society of South Africa, 2012-06)
    This paper explores the effectiveness of usage control deterrents. Usage control enables finer-grained control over the usage of objects than do traditional access control models. Deterrent controls are intended to ...
  • Evolving behavioral specialization in robot teams to solve a collective construction task 
    Nitschke, G.S.; Schut, M.C.; Eiben, A.E. (Elsevier, 2012-02)
    This article comparatively tests three cooperative co-evolution methods for automated controller design in simulated robot teams. Collective Neuro- Evolution (CONE) co-evolves multiple robot controllers using emergent ...
  • Evolving robot sub-behaviour modules using Gene Expression Programming 
    Mwaura, Jonathan; Keedwell, Ed (Springer, 2015-05)
    Many approaches to AI in robotics use a multi-layered approach to determine levels of behaviour from basic operations to goal-directed behaviour, the most well-known of which is the subsumption architecture. In this ...
  • Extending backward polygon beam tracing of glossy scattering surfaces 
    Duvenhage, B.; Bouatouch, K.; Kourie, Derrick G. (Wiley-Blackwell, 2011)
    Backward polygon beam tracing methods, that is beam tracing from the light source (L), are well suited to gather path coherency from specular (S) scattering surfaces. These methods are useful for modelling and efficiently ...
