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":["s5","m5","f5","d5"],"alphabet":["a5","b5"],"start_state":"s5","final_states":["f5"],"transitions":[["s5",null,"m5"],["s5",null,"d5"],["m5","a5","m5"],["m5","b5","f5"]]}。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":["s5","m5","f5","d5"],"alphabet":["a5","b5"],"start_state":"s5","final_states":["f5"],"transitions":[["s5",null,"m5"],["s5",null,"d5"],["m5","a5","m5"],["m5","b5","f5"]]}。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]=[s5, null, m5];state carrier=[s5, m5, f5, d5];alphabet=[a5, b5]

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]=[s5, null, d5];state carrier=[s5, m5, f5, d5];alphabet=[a5, b5]

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]=[m5, a5, m5];state carrier=[s5, m5, f5, d5];alphabet=[a5, b5]

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, S003

S005 · implies

操作前

ORIGINAL transition index=3;[from,input_or_null,to]=[m5, b5, f5];state carrier=[s5, m5, f5, d5];alphabet=[a5, b5]

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=[s5, m5, f5, d5],alphabet=[a5, b5],start=s5,final_states=[f5];complete relation=[[s5, null, m5], [s5, null, d5], [m5, a5, m5], [m5, b5, f5]]

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=[s5, m5, f5, d5];ORIGINAL alphabet order=[a5, b5];complete relation=[[s5, null, m5], [s5, null, d5], [m5, a5, m5], [m5, b5, f5]]

操作後

ALL [state,symbol,ORIGINAL-order targets] rows=[[s5, a5, []], [s5, b5, []], [m5, a5, [m5]], [m5, b5, [f5]], [f5, a5, []], [f5, b5, []], [d5, a5, []], [d5, b5, []]];EMPTY target rows=[[s5, a5, []], [s5, b5, []], [f5, a5, []], [f5, b5, []], [d5, a5, []], [d5, b5, []]];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
