  • G001 — deterministic single-tape signature、exact configuration semantics與decider total-correctness boundary。操作=tm-exact-step-trace;資料={"states":["q023","q123","qa23","qr23"],"input_alphabet":["023"],"tape_alphabet":["023","X23","_23"],"blank":"_23","start_state":"q023","accept_state":"qa23","reject_state":"qr23","transitions":[["q023","023","q123","X23","R"],["q023","_23","qr23","_23","S"],["q123","_23","qa23","_23","L"]],"input":["023"],"steps":2}。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 roles = [tm-exact-step-trace]

操作後

derived = [[input, step_budget, configurations, step_outcomes, final_state, local_outcome, global_decider_certificate, boundary]]

條件:無

直接列來源完整欄序,不需JavaScript;原題、布林旗標、數學物件與非聲稱保持分層。

步驟識別與依賴

規則:source_ordered_fields_without_JS · 依賴:G001

S002 · implies

操作前

source roles = [[q023, q123, qa23, qr23], [023], [023, X23, _23], _23, q023, qa23, qr23, [[q023, 023, q123, X23, R], [q023, _23, qr23, _23, S], [q123, _23, qa23, _23, L]]]

操作後

derived = [[q023, q123, qa23, qr23], [023], [023, X23, _23], [[q023, _23, qr23, _23, S], [q023, 023, q123, X23, R], [q123, _23, qa23, _23, L]], 是]

條件:無

三個清單皆非空且唯一;input是blank-free tape子集,但state與字母標籤不要求不相交。每個(from,read)的來源NUL-joined key唯一、halt無出邊。partial table合法,不補reject規則;canonical transition序與UTF16集合序分開。

步驟識別與依賴

規則:TM_complete_signature_partial_transition_table_allowed · 依賴:G001, S001

S003 · implies

操作前

source roles = [[023], q023, _23]

操作後

derived = [[q023, 0, [[0, 023]]]]

條件:無

初始head0、input放0起的整數格,其餘全blank;稀疏記錄僅保非blank。tape可往負index伸展。

步驟識別與依賴

規則:TM_exact_initial_configuration_blank_elsewhere · 依賴:G001, S002

S004 · calculation

操作前

TM exact integer head move0 := sum(0, 1)

操作後

TM exact integer head move0 = 1

條件:無

依原始角色與已證中間量精確代值,分母先核非零,不用浮點近似。

步驟識別與依賴

規則:exact_rational_arithmetic · 依賴:G001, S003

S005 · implies

操作前

source roles = [0, [q023, 0, [[0, 023]]], 023, [q023, 023, q123, X23, R]]

操作後

derived = [step, [q123, 1, [[0, X23]]]]

條件:無

先在舊head寫字(blank刪格),再換state及移head;全部L/R/S按原rule,不混成停機語意。

步驟識別與依賴

規則:TM_source_rule_exact_read_write_state_move · 依賴:G001, S004

S006 · calculation

操作前

TM exact integer head move1 := sum(1, -1)

操作後

TM exact integer head move1 = 0

條件:無

依原始角色與已證中間量精確代值,分母先核非零,不用浮點近似。

步驟識別與依賴

規則:exact_rational_arithmetic · 依賴:G001, S005

S007 · implies

操作前

source roles = [1, [q123, 1, [[0, X23]]], _23, [q123, _23, qa23, _23, L]]

操作後

derived = [step, [qa23, 0, [[0, X23]]]]

條件:無

S008 · implies

操作前

source roles = [[023], 2, [[q023, 0, [[0, 023]]], [q123, 1, [[0, X23]]], [qa23, 0, [[0, X23]]]], [step, step]]

操作後

derived = [qa23, accept, 否]

條件:無

已halt才接受/拒絕;budget用盡或stuck不是普通reject,也不證永久不停止。一個input的有限trace不提供all-input decider證書。

步驟識別與依賴

規則:TM_finite_trace_input_budget_scope_NOT_global_decider · 依賴:G001, S007
