  • An AI search algorithm to obtain the shortest simplex path 
    Scott, TG; Hattingh, J.M.; Steyn, T (South African Computer Society (SAICSIT), 1996)
    The simplex method is one way of solving a linear programming problem (LP-problem). An A* search algorithm based on a certain evaluation function has been developed to obtain the shortest path to an optimal solution within ...
  • Cardinality constrained 0-1 Knapsack problems 
    Kruger, MF; Hattingh, JM; Steyn, T (2000)
    The Knapsack Problem is one of the most important problems in Discrete optimization. Although it is the simplest integer program, it has numerous practical applications and often appears as a subproblem in solving more ...
  • Die versoening van konflikterende doelwitte in die databasisomgewing met behulp van regressiemetodes 
    Jordaan, DB; Hattingh, J.M.; Steyn, T (South African Computer Society (SAICSIT), 1993)
    Daar bestaan baie voorbeelde in die dataverwerkingswêreld van gebruikers wat nie die inligting vanuit huIlle rekenaarstelsels kry wat hulle nodig het nie [26]. Nuwe en onvoorsiene vrae en versoeke vir inligting neem by die ...
  • The feasibility problem in the simplex algorithm 
    Scott, TG; Hattingh, JM; Steyn, T (1996)
    The simplex method is one way of solving a linear programming problem (LP-problem). The simplex method needs a basic feasible solution to start the solution process. This requires an available non-singular basis. Normally ...
  • Linear response surface analysis and some applications 
    Hattingh, JM (2000)
    In general response surface analysis refers to the modeling of experimental or observational data. Computer technology and graphical techniques obviously play a significant role in the representations of these models. A ...
  • Models to evaluate the state of computer Facilities at South African universities 
    Bruwer, P.J.S.; Hattingh, J.M. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    Computer technology has grown exponentially in the course of the past decade in terms of sophistication - not only with regard to hardware and networks, but also with regard to mainframe and micro-computer systems. ...
  • A partitioning scheme for solving the exact K-item 0-1 knapsack problem 
    Kruger, MF; Hattingh, JM (1998)
    Our investigation on the impact of partitioning the search space of the classical 0- 1 Knapsack Problem through the inclusion of equality constraints on the knapsack's cardinality, has given rise to the study we undertook ...
  • A risk model to allocate resources to different computerised systems 
    Kruger, HA; Hattingh, JM (1997)
    The majority of large organisations operate and maintain significant portfolios of computerised systems. All Information Systems (IS) managers are increasingly faced with the task of doing more with less. To cope with ...
