CLIPS Environment:

"Watch" activations and rules (Execution-Menu).
Open "Agenda" and "Facts" windows in Window-Menu.
Try the "Step" function (Execution-Menu) to see how facts and activations change in each pattern matching-activation-firing cycle.

Labs:

• Lab 1
  • Tasks (doc) (pdf)
• Lab 2
  
  • Explore "Complex Condition Elements", see Course Notes CLIPS Intro-2, slides 16-20.
    Do the task on slide 24. There are several options to write the pattern more efficiently.
    Explore the Constraint Checking options on the CLIPS Command level (Execution Menu).
  • Tasks (doc) (pdf)
  • Example code "Course"
    • Templates and Facts (clp)
    • Simple Rule (clp)
    • Rule with Input (clp)
  • Example code "Birthday"
    • Student Template (clp)
    • Student Facts (clp)
    • Birthday Rule (clp). You have to assert birthday-fact!
    • Old-Students Rule (clp). Has test-condtion for age.
  • Example code "Find Person"
    • Find Person (clp)
    • Find Person 2 (clp)
• Lab 3
  
  • We work with forall and exists and explore more "Complex Condition Elements", and we will use input through "read".
    See the Course Notes CLIPS Intro-2, slides 20ff.
    
  • Tasks (doc) (pdf)
  • Example code "Emergency"
    • Simple-Emergency (directory)
    • UofM-Emergency (directory)
    • Note: global variables do NOT invoke a new pattern matching process when changed.
      see CLIPS Basic Programming Guide, p.66
• Lab 4
  
  • We look at "Control in Rule-Based Systems".
    See the Course Notes Rule-Based Systems Control.
    
  • Tasks (doc) (pdf)
  • Example code "Phases"
    • Phases using tags in rules (clp)
    • Phases using salience (clp)
    • Phases using modules (clp)
  • Examples
    • Wine (txt)
    • Mud (txt)
