|

|
||||
Atomic propositions can be removed from an automaton in three ways:
|
||||
- use ~--remove-ap=a~ to remove =a= by existential quantification, i.e., both =a= and its negation will be replaced by true.
|
||||
This does not remove any transition.
|
||||
- use ~--remove-ap=a=0~ to keep only transitions compatible with =!a= (i.e, transitions requiring =a= will be removed).
|
||||
- use ~--remove-ap=a=1~ to keep only transitions compatible with =a= (i.e, transitions requiring =!a= will be removed).
|
||||
|
||||
Here are the results of these three options on our example:
