Time for Autotmata

We know that for dfa

d or transition function is defined as

q x s->q
where q is the set of all the states and s is the set of input symbols

and in nfa

d is defined as

q x s->2^q


what do you interpret by this?

  1. its just that for a given state and an input symbol there can be more than 1 transitions....thats what a nfa is i guess....or i guess the question is not clear to me.....and 2^q is for all the subsets of q....am i right khush??

  2. YA and how do you say that all the subset of q will be 2^q waise this question is just related to combination

  3. ok i interpreted the powerset sort as the sum of different combinations
    c0+c1+c2+c3+.......+cn = 2^n
