Abstract
A method and apparatus for detecting an endless loop in a rules-based expert system. This is preferably accomplished by maintaining a count for each of the rules during rule processing. The count indicates the number of times a corresponding rule is executed by the rules based expert system. If the count corresponding to any of the rules exceeds a predetermined value, it is concluded that the rules-based expert system is stuck in an endless loop, and the rules-based expert system is interrupted.
