Use a complete deterministic finite automaton with states=Fin(3)={0,…,2}, alphabet=Fin(2)={0,…,1}, total row-state/column-symbol transition=[[2, 1], [0, 0], [0, 0]], unique start=2, and increasing accepting subset=[2]. Every transition output lies in this same state set. There are no epsilon transitions or nondeterministic branches. Read a finite word in symbol order; the empty word leaves the automaton at its start state. Word=[1, 0, 1, 0, 0]. Give (word,state_trace,final_state,accepted?).
G001 — Use a complete deterministic finite automaton with states=Fin(3)={0,…,2}, alphabet=Fin(2)={0,…,1}, total row-state/column-symbol transition=[[2, 1], [0, 0], [0, 0]], unique start=2, and increasing accepting subset=[2]. Every transition output lies in this same state set. There are no epsilon transitions or nondeterministic branches. Read a finite word in symbol order; the empty word leaves the automaton at its start state. Word=[1, 0, 1, 0, 0]. Give (word,state_trace,final_state,accepted?).Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
Before
DFA total state-symbol cell count := mul(3, 2)
After
DFA total state-symbol cell count = 6
Conditions: none
Compute exactly from original field roles and established intermediates,retaining denominators,signs,indices and the complete carrier.

same complete states Fin(3);alphabet Fin(2);row-state column-symbol table=[[2, 1], [0, 0], [0, 0]]
After
single original start=2;canonical accepting subset=[2];required transition cells=6
Conditions: none
Fix states,alphabet,one start state and accepting subset.Rows index states and columns index symbols;every output must remain in the same state set.Check the whole table,not just cells visited by this word.

Before
original ordered word=[1, 0, 1, 0, 0];original start=2
After
initial trace before consuming any symbol=[2]
Conditions: none
Place the initial state in the trace before reading symbols.The empty word consumes nothing and performs no invented transition;its final state is the start.
Rule: dfa_initial_state_before_first_symbol_including_empty_word · Uses: G001, S008
Before
word position=0;original symbol=1;current state=2;original state row=[0, 0]
After
lookup column=1;next state=0;prefix trace=[2, 0]
Conditions: none
Read the original symbol order with one column lookup per symbol.Do not reverse the word or swap state/symbol roles.Each consumed symbol adds one state,so trace length is word length plus1.
