Methods, systems, and devices supporting epsilon (ε)-closure for frequent pattern (FP) analysis are described. Some database systems may analyze data sets to determine FPs. In some cases, the FP set may include a large number of semi-redundant patterns, resulting in significant memory or ...

The first step comprises computing for each state “p” of the automaton A its ε-closure. The second step in the method comprises modifying the outgoing transitions of each state “p” by removing those labeled with ε. The method next comprises adding to the set of transitions leaving the...

Conclusion In this chapter, we explained in detail how to convert an epsilon NFA to DFA. We know the NFA may have multiple states from one state with same input and may have null transitions. But in DFA, there will be no null transitions. We have seen this through an example and learnt...
