Abstract
A representation of a new rule, defined as a set of a new transition(s), is inserted into a perfect hash table which includes previously placed transitions to generate an updated perfect hash table. This may be done by, for each new transition: (a) hashing the new transition; and (b) if there is no conflict, inserting the hashed new transition into the table. If, however, the hashed new transition conflicts with any of the previously placed transitions, either (A) any transitions of the state associated with the conflicting transition are removed from the table, the hashed new transition is placed into the table, and the removed transitions are re-placed into the table, or (B) any previously placed transitions of the state associated with the new transition are removed, and the transitions of the state associated with the new transition are re-placed into the table.
