The following automaton has states that cannot be reached from the initial(s) states:
In [2]:
%%automaton a
context = "lal_char(abc), b"
$ -> 0
0 -> 1 a
1 -> $
2 -> 0 a
1 -> 3 a
In [3]:
a.is_accessible()
Out[3]:
Calling accessible
returns a copy of the automaton without non-accessible states:
In [4]:
a.accessible()
Out[4]:
In [5]:
a.accessible().is_accessible()
