There is a large literature concerning rule engines (forward chaining or backward chaining). During the last thirty years there were various proposals such as RETE, TREAT and the derived Gator algorithm. Significantly, RETE was embedded into various expert systems such as Clips and its successor Jess, and Drools including in a number of commercial rule engines and was extended various times inc...

In the last decade, there have been people whose style of play effects are online. This online gamewill be a very middle thing, because this opium could husband with no real life, nor cause death. There suspected cancer victims games need to consult problem on. But many factors pakah come pakkes, such as lazy, time, our timing so cost. Therefore, system experts diagnose using backward chaining ...

Both materialization and backward-chaining as different modes of performing inference have complementary advantages and disadvantages. Materialization enables very efficient responses at query time, but at the cost of an expensive up front closure computation, which needs to be redone every time the knowledge base changes. Backward-chaining does not need such an expensive and change-sensitive p...

The problem of detecting feature interactions in telephone systems design is addressed. The method proposed involves specification of the features in LOTOS, and uses an analysis technique called backward reasoning. This is is implemented in LOTOS by a combination of backward and forward execution. A tool to help carry out backward execution is presented. A detailed example of the use of the tec...

Linearizability is the standard correctness criterion concurrent datastructures such as stacks and queues. It allows to establish observational refine-ment between a concurrent implementation and an atomic reference implemen-tation. Proving linearizability requires identifying linearization points for eachmethod invocation along all possible computations, leading to valid sequen...
