shortest_string(G,m,n)

generate a shortest string from state m (which need not be the initial state) to another (reachable) state n

Name	Type	Description	Default
`G`	string	name of DES	required
`m`	int	state number	required
`n`	int	state number	required

Example

sample 1

delta = [
    (0, 11, 1),
    (1, 12, 2),
    (2, 11, 0),
    (2, 14, 3)
]
Qm = [3]
pitct.create('G', 4, delta, Qm)

pitct.shortest_string('G',1,3)
