  • Assessing the usability of computer systems 
    Parker-Nance, TC; Warren, PR (South African Computer Society (SAICSIT), 1993)
    Usability problems with computer systems can be divided into three broad categories: problems due to the socio/political environment, problems due to the usefulness of systems, and problems due to the accessibility of ...
  • A comparison of graph colouring techniques 
    Parkinson, E; Warren, PR (South African Computer Society (SAICSIT), 1995)
    Many scheduling problems can be modelled as graph colouring problems. This paper gives a survey of heuristic algorithms used to colour graphs by describing a number of such algorithms found in the literature using an ...
  • Design patterns for user interfaces 
    Warren, PR; Viljoen, M (1998)
    This work reports on 23 third year student' s projects in which the user interfaces (UI) were found wanting. We show in which ways we regard the UI to be in error. However, an examination of the available literature on UI ...
  • Examination timetabling 
    Parkinson, E; Warren, PR (1996)
    We investigate the performance of simulated annealing and tabu search, two new general problem solving heuristics, on an examination timetabling problem. These two techniques are described here and issues arising from ...
  • An investigation in the separation of the application from its user interface 
    Greyling, JH; Warren, PR (South African Institute of Computer Scientists and Information Technologists, 1991)
    The separation of an interactive program's application from its user interface is investigated. In order to support good human interaction, the interface requires a deep knowledge of the application. This is in direct ...
