Questions about automata, formal grammars or other computation-models that specifically relate to the use of nondeterminism. Not to be confused with randomness or ambiguity!
See here for why and in which way nondeterminism and randomness are not the same!
Fitting category tags are automata and/or computation-models. Other related tags include finite-automata, pushdown-automata, linear-bounded-automata, turing-machines, cellular-automata, formal-grammars, and probably more.
Note that in the context of grammars, nondeterminism should not be confused with ambiguity, either!
