Abstract
The invention implements a novel method for discarding model behaviors from the computation-tree, when these behaviors are defined by the user as ‘not interesting’. The method works as follows: the user defines, by declarative means via regular expression, a set of model behaviors that are of interest. After applying this method, referred to as the restrict algorithm henceforth, the computation-tree will consist only of paths representing model behaviors specified by the user. The restrict algorithm consists of a preprocessing stage and a processing stage. In the preprocessing stage, a mechanism for identifying when an execution path is an allowed behavior is constructed. While processing, sub-trees representing “bad behaviors” (execution paths identified as not allowed behaviors) are pruned from the computation-tree.
