"How did the procedure look for a complete automaton of size 5 when the input had only 2 states? It's because the input uses transition-based acceptance: to estimate an upper bound of the size of the state-based output, the `sat_minimize()` procedure converted its transition-based input to state-based acceptance (using the `spot.sbacc()` function) and counted the number of states in the result.\n",
"\n",
"Such an estimate is not necessarily correct of we request a different acceptance condition. In that case We can actually change the upper-bound using `max_states`. Below we additionally demonstrate the use of the `colored` option, to request all transition to belong to exactly one set, as customary in parity automata."

"Sometimes we do not want a minimization loop, we just want to generate an equivalent automaton with a given number of states. In that case, we use the `states` option. However there is no constraint that all state should be reachable, so in the end, you could end with an automaton with fewer states than requested."
