Diagnosis of multiple diseases in large medical expert systems based on causal probabilistic networks may require resources that are not available on common computers. We propose a method that is able to diagnose multiple diseases by systematic investigation of subsets of diseases. The method is illustrated in the MUNIN expert system for diagnosis of muscle and nerve diseases. In MUNIN the requirements for memory space and calculation time were reduced by about 5 orders of magnitude, which is sufficient to make the method practical. We conclude that the method is viable under reasonable assumptions.
