  • Application-oriented program semantics 
    McIver, AK; Morgan, C; Sanders, JW (South African Computer Society (SAICSIT), 1997)
    This paper abridges lecture notes from WOFACS 96. It provides semantic models for a variety of programming and development formalisms, showing how different models for the same formalism are related by Galois connections. ...
  • pGCL: formal reasoning for random algorithms 
    Morgan, C; McI, A (South African Computer Society (SAICSIT), 1998)
    Dijkstra's guarded-command language GCL contains explicit 'demonic' nondeterminism, representing abstraction from (or ignorance of ) which of two program fragments will be executed. We introduce probabilistic nondeterminism ...
  • The refinement calculus 
    Morgan, C (South African Computer Society (SAICSIT), 1995)
    The refinement calculus, based on weakest preconditions, elaborates imperative program developments as a series of steps linked by a mathematical refinement relation. Specifications and executable code are regarded equally ...
