原題與已知條件

transition=[from,input-or-null,to]且允許empty alphabet/final set的finite epsilon-NFA。操作=nfa-qualification;資料={"states":["s20","m20","f20","d20"],"alphabet":["a20","b20"],"start_state":"s20","final_states":["f20"],"transitions":[["s20",null,"m20"],["s20",null,"d20"],["m20","a20","m20"],["m20","b20","f20"]]}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

  • G001 — transition=[from,input-or-null,to]且允許empty alphabet/final set的finite epsilon-NFA。操作=nfa-qualification;資料={"states":["s20","m20","f20","d20"],"alphabet":["a20","b20"],"start_state":"s20","final_states":["f20"],"transitions":[["s20",null,"m20"],["s20",null,"d20"],["m20","a20","m20"],["m20","b20","f20"]]}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

定義與適用範圍

沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核,並由原始參數逐題獨立重算模型、答案與每個算術步驟;原題仍為 candidate。

逐步推導

S001 · implies

操作前

source operation=nfa-qualification;original snapshot and mathematics retained

操作後

explicit ordered source output fields=[states, alphabet, start, final_states, transitions, empty_target_rows, qualified, convention]

條件:無

原題快照保留歷史介面;此處直接列來源欄序,不依賴JavaScript。tag與No保聲稱範圍,固定來源排序不冒充數學證明。

步驟識別與依賴

規則:source_ordered_interface_explicit_without_javascript · 依賴:G001

S002 · implies

操作前

ORIGINAL transition index=0;[from,input_or_null,to]=[s20, null, m20];state carrier=[s20, m20, f20, d20];alphabet=[a20, b20]

操作後

state endpoints legal;symbol either declared input or null EPS consuming0;ORIGINAL row position retained,including duplicate rows

條件:無

這是relation不是單值total函數,duplicate/多值/缺邊皆保原資料;null消耗0但不是一個alphabet字串。

步驟識別與依賴

規則:nfa_EVERY_original_relation_row_roles_empty_multi_EPS_legal · 依賴:G001, S001

S003 · implies

操作前

ORIGINAL transition index=1;[from,input_or_null,to]=[s20, null, d20];state carrier=[s20, m20, f20, d20];alphabet=[a20, b20]

操作後

state endpoints legal;symbol either declared input or null EPS consuming0;ORIGINAL row position retained,including duplicate rows

條件:無

這是relation不是單值total函數,duplicate/多值/缺邊皆保原資料;null消耗0但不是一個alphabet字串。

步驟識別與依賴

規則:nfa_EVERY_original_relation_row_roles_empty_multi_EPS_legal · 依賴:G001, S002

S004 · implies

操作前

ORIGINAL transition index=2;[from,input_or_null,to]=[m20, a20, m20];state carrier=[s20, m20, f20, d20];alphabet=[a20, b20]

操作後

state endpoints legal;symbol either declared input or null EPS consuming0;ORIGINAL row position retained,including duplicate rows

條件:無

這是relation不是單值total函數,duplicate/多值/缺邊皆保原資料;null消耗0但不是一個alphabet字串。

操作前

ORIGINAL transition index=3;[from,input_or_null,to]=[m20, b20, f20];state carrier=[s20, m20, f20, d20];alphabet=[a20, b20]

操作後

state endpoints legal;symbol either declared input or null EPS consuming0;ORIGINAL row position retained,including duplicate rows

條件:無

這是relation不是單值total函數,duplicate/多值/缺邊皆保原資料;null消耗0但不是一個alphabet字串。

步驟識別與依賴

規則:nfa_EVERY_original_relation_row_roles_empty_multi_EPS_legal · 依賴:G001, S004

S006 · implies

操作前

ORIGINAL states=[s20, m20, f20, d20],alphabet=[a20, b20],start=s20,final_states=[f20];complete relation=[[s20, null, m20], [s20, null, d20], [m20, a20, m20], [m20, b20, f20]]

操作後

states nonempty with actual start;alphabet/final set/relation MAY be EMPTY;definition qualification does NOT prove determinism,totality,DFA equivalence or a successful run

條件:無

空final set合法且辨識空語言;空alphabet也合法。定義合格不保存在accepting path,亦不推deterministic或DFA等價。

步驟識別與依賴

規則:nfa_qualified_definition_EMPTY_alphabet_finals_edges_allowed · 依賴:G001, S005

S007 · implies

操作前

ORIGINAL state order=[s20, m20, f20, d20];ORIGINAL alphabet order=[a20, b20];complete relation=[[s20, null, m20], [s20, null, d20], [m20, a20, m20], [m20, b20, f20]]

操作後

ALL [state,symbol,ORIGINAL-order targets] rows=[[s20, a20, []], [s20, b20, []], [m20, a20, [m20]], [m20, b20, [f20]], [f20, a20, []], [f20, b20, []], [d20, a20, []], [d20, b20, []]];EMPTY target rows=[[s20, a20, []], [s20, b20, []], [f20, a20, []], [f20, b20, []], [d20, a20, []], [d20, b20, []]];no missing edge repaired

條件:無

逐原state再原symbol列全部target,保原transition次序與重複;空target不是不合格。空alphabet時沒有這類pair,空final set亦不變成任意accept。

步驟識別與依賴

規則:nfa_ORIGINAL_state_symbol_relation_targets_not_totality_assumption · 依賴:G001, S006
