Integration of CSP and CBR to Compensate for Incompleteness and Incorrectness of Models

Mohammed H. Sqalli and Eugene C. Freuder

Modeling is very useful in many domains. A model can be very simple such as a mathematical equation, or be very complex. But, models are not always perfect and may not represent all the information about the system. In this paper, we suggest compensating for incompleteness and incorrectness of models by integrating Constraint-Based and Case-Based Reasoning. We model the problem as a Constraint Satisfaction Problem (CSP), then Case-Based Reasoning (CBR) used to compensate for what is missing in this model. CBR supports the process of learning by supplying the case-base with new cases that can be used to solve future similar problems. CBR is also used to update the CSP model, and make it more robust for solving more problems. The domain we are using is InterOperability Testing of protocols in ATM (Asynchronous Transfer Mode) networks.
