A rule consists of a precondition (premise) and an action. The precondition describes a situation in which the action is to be performed. There are two types of action:
  • Implications, with which the truth of a statement is derived (Rule (1) in Fig. 5.1) and

  • Instructions for changing a state (Rule (2) in Fig. 5.1).
