Hi,

I'm trying to finish off an expert system for selecting engineering materials. I
have an object which is passed a vector of materials and the expert system
returns their suitability using store-fetch. The rete object (materials
decider) is used in a method called getAcceptibility which batches the rules
located in rules.clp everytime the method is called. This approach works fine
but it is REALLY slow.

Is there anyway of speeding this up? I tried batching the rules in the
constructor of the class and it is dramatically faster but store-fetch doesn't
work properly then. This results in every material given the same suitability
(20%). I tried to remedy this by clearing the storage of rule engine using
clearStorage but this throws up a null-pointer exception.

Is there anything else I can try?
