The path function δ : Q × Σ*→ P(Q) is the extension of δ to strings:
Again, this just says that to ?nd the set of states reachable by a path labeled w from a state q in an NFA with ε-transitions start by ?nding the set of states reachable from q using only ε-transitions and then, for each symbol σ of w (in order) ?nd the set of states reachable from those by an edge labeled σ and then the set of states reachable from those by any sequence of ε-transitions, etc.
Nothing else in the de?nitions need change. The automaton still accepts w if there is any computation on (q0,w) that terminates in a ?nal state after scanning the entire input. Equivalently, it accepts w if there is a path labeled w from the initial state to a ?nal state, which is to say, if δ(q0,w) includes any member of F. Note that the automaton of the example above will accept ‘ε' since state 2 is in ε-Closure(0) and, therefore in δ(0, ε).

Normal forms are important because they give us a 'standard' way of rewriting and allow us to compare two apparently different grammars G1 and G2. The two grammars can be shown to
Strictly 2-local automata are based on lookup tables that are sets of 2-factors, the pairs of adjacent symbols which are permitted to occur in a word. To generalize, we extend the
We got the class LT by taking the class SL and closing it under Boolean operations. We have observed that LT ⊆ Recog, so certainly any Boolean combination of LT languages will also
The computation of an SL 2 automaton A = ( Σ, T) on a string w is the maximal sequence of IDs in which each sequential pair of IDs is related by |- A and which starts with the in

Let there L1 and L2 . We show that L1 ∩ L2 is CFG . Let M1 be a decider for L1 and M2 be a decider for L2 . Consider a 2-tape TM M: "On input x: 1. copy x on the second

Our DFAs are required to have exactly one edge incident from each state for each input symbol so there is a unique next state for every current state and input symbol. Thus, the ne
Automaton (NFA) (with ε-transitions) is a 5-tuple: (Q,Σ, δ, q 0 , F i where Q, Σ, q 0 and F are as in a DFA and T ⊆ Q × Q × (Σ ∪ {ε}). We must also modify the de?nitions of th
