State q0 has a transition that is labeled not by an input symbol in {0, 1} but by ϵ This is an example of what is called a nondeterministic finite automaton (NFA)

We call this a non-deterministic finite automata (NFA). We say it accepts input x if and only if there exists a path that accepts x. What is the language of
Finite automata running on infinite trees originally introduced by Rabin in his seminal work [15] are now widely considered as one of the key paradigms for.
Nondeterministic Finite Automata (NFA). Jay Bagga. 1 Introduction. In the module on Deterministic Finite Automata (DFA) you learned that a DFA is a finite.
Saturate the given automata with respect to bisimulation equivalence or simulation preorder. An alternative approach to checking NFA equivalence is to use
