## [turing-machine](https://github.com/lxylxy123456/turing-machine)
Python implementation of DFA and Turing Machine

DFA Demo: test whether the input binary string represents a number divisible by 3

* Specification
```
DFA_3mod = {
	'Sigma': 	(0, 1), 
	'Q': 		('A', 'B', 'C'), 
	'q0':		'A', 
	'F': 		('A',), 
	'delta': 	{
					('A', 0): 'A', 
					('A', 1): 'B', 
					('B', 0): 'C', 
					('B', 1): 'A', 
					('C', 0): 'B', 
					('C', 1): 'C', 
				}, 
}
```
* Plot

Turing Machine Demo: [2nd busy beaver](https://en.wikipedia.org/wiki/Busy_beaver#Examples)

* Specification
```

					('A', 1): ('B', 1, L), 
					('B', 0): ('A', 1, L), 
					('B', 1): ('H', 1, R), 
				}, 
}
