What exactly is pumping length?
The pumping length is any number the number of states in the smallest finite state machine for the language. (Except that we don't greater than that number of states, and we usually use the pumping Lemma to show that the language is irregular and therefore the number of states and the pumping length don't exist).7 mai 2022
If A is a regular language, then there is a number p where if s is any string in A of length at least p, then s may be divided into three pieces, s = xyz, satisfying the following conditions: for each i ≥ 0, xyiz ∈ A.
Is pumping length equal to number of states?
If n is the number of states of the minimal automaton of L, then one can choose n for the pumping length.
However, it may happen that the mimimal possible pumping length is strictly smaller than n.
