Increasing the length results in making the computing of the hash code too slow for practical use.Īnother approach was having a set of words and testing which of them the automaton accepts but finding the right ones, I think, isn't that trivial.
But it seems to produce too many collisions on NFAs with 4 states. For a transition afat1.png, A nondeterministically chooses to switch the state to either q1 or q2. We give a new, general method of analysis of these systems. 5 and then I map the set of accepted words to a 64-bit long (the amount of binary words of length max. Alternating Finite Automata (AFA) In automata theory, an alternating finite automaton (AFA) is a non-deterministic finite automaton whose transitions are divided into existential and universal transitions. This method makes use of finite state automata-one associated with each agent-which guide the agents. My first thought was doing a DFS on the transitions and finding all the accepted words until length max. nite state automaton) is an abstract device (simpler than a Turing machine). Follow the steps: Start from the first production And then for every left alphabet go to SYMBOL followed by it Start State: It will be the first productions state Final State: Take those states which end up with input alphabets. Therefore, I have to use some good hash function, to avoid compairing with too many automatas. Finite State Machines (FSMs) AFinite State Machine(a.k.a. Converting right linear grammar to Finite Automata is simple. I'm working on project in Java (but I think it doesn't depend on the language) where I'm generating small (4 states max) nondeterministic finite state automata on binary alphabet and I have to check fast the generated automaton for equivalence with the previous ones.
