Ns2 project in perth
Ns2 project in perth the semantics of metarules dictates that when there are two or more conflicting rule instances, some particm lar ns2 project in perth instance should be redacted. Can we define a total ordering over rule instances and use lazy matching ns2 project in perth at the network nodes applied to instances so that only the single rule instanc,e that would be fired is generated and those that would be redacted would not even be generated? The answer is no. Preference here is not dependent upon lexicographic sort of ns2 project in perth a totally ordered WM as in OPS5.
Preference here meansprogrammer supplied preference based upon arbitrary conditions on bound values in instances that are dynamically ns2 project in perth computed and that, may not define a total ordering. It is unlikely that lazy match will be effective in systems with set-oriented semantics as described here. Our goal is to compute and execute as many instances, and thus as many working memory transactions, in ns2 project in perth a single inference cycle as possible.
We do not seek to compute a single firable rule as quickly as possible in a single inferenc,e c,yc.le by reducing the ns2 project in perth amount of irrelevant match work as in lazy evaluation. Rather, we attempt ns2 project in perth to make all match work as relevant as possible by eliminating conflicting rule instances according to a set of user specified metarules. Another possible metarule implementation discussed in is as follows. We compile the rnetarules into object level rules while rewriting the object level rules mentioned in the metarules. Here, the object level rules are changed so ns2 project in perth that they always fire but assert an “instance’ object in the object level WM. Metarules match against these instance objects, and when a metarule fires, its actions are not redactions, but the RHS actions of the rules that they would have allowed to fire.
