Symbolic Programming

• The major learning outcomes for this module revolve around Symbolic Programming:
  • Rule Based Systems
  • Case Based Reasoning Systems
• In both types of systems, the primitives are symbols.
• We've also called symbols features.
• In RBS systems these are the working memory items.
• In CBR systems they are the features that each case is made of.
• RBS and CBR systems differ in the way they use these symbols.
• RBS systems use rules whose if clause is based on the current state of the symbols (WM); the then clause may change the symbols (WM)
• A CBR system compares a new tuple of symbols (a case) with all of the old tuples (the case base) and finds the one nearest.
• In addition to being able to use these systems, you should know when to use them, and some software engineering concepts for their development.
