WebFor a human, there can be two states: hungry, not hungry A basket can have only one item from: apple, orange. So, to model it we will have: hungry->pick from basket->apple found. hungry->pick from basket->orange found. apple found->eat->not hungry. orange found->take juice out of it and then drink-> not hungry

Can DFA have multiple inputs? – WisdomAnswer

WebJun 8, 2024 · Can a DFA have multiple initial states? DFA can only have one initial state, but can have zero, one or more than one final states over any number of input alphabet. When do you move from NFA to DFA? In DFA, on input 0 from state [A, B], we can move to state [A, B, C]. This step follows for all states of DFA. Web@mAhMoUdDaFeR My point is it's possible to formally define NFAs in such a way that multiple initial states are admissible, but it's probably not possible to do so for DFAs in … can heart arrhythmia cause death

WebAug 16, 2016 · If you really have a DFA you will not have multiple active states. A DFA is defined to have exactly one active state. And each character can only lead to exactly the next state. If you take this property, you start from the … WebA DFA represents a finite state machine that recognizes a RE. For example, the following DFA: recognizes ( abc+) +. A finite automaton consists of a finite set of states, a set of transitions (moves), one start state, and a set of final states (accepting states). In addition, a DFA has a unique transition for every state-character combination.
