Recognise Act Cycle

• Rule Based Systems work on a Recongise Act Cycle
• Roughly, rules are recognised as firable.
• A rule is applied, which may or may not change working memory
• It may have side effects (e.g. print something out or move a robot arm)
• A new set of rules is recognised
• If no rules apply the system is done.
• Why?
• This can change if the system is interactive.
• If it is interactive, WM can change because of the interface and new rules can be applied.
