第 25097 題：線性規劃標準形

原題與已知條件

固定maximize cTx、Ax≤b、x≥0的唯一standard-form convention。操作=lp-standard-unrestricted-split；資料={"column":[22,-23,24],"objective_coefficient":25,"value":-22}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

• G001 — 固定maximize cTx、Ax≤b、x≥0的唯一standard-form convention。操作=lp-standard-unrestricted-split；資料={"column":[22,-23,24],"objective_coefficient":25,"value":-22}。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

source roles = [lp-standard-unrestricted-split]

derived = [[column, objective_coefficient, value, x_plus, x_minus, reconstructed_value, original_column_contribution, split_column_contribution, columns_equal, original_objective_contribution, split_objective_contribution, objectives_equal, certificate]]

LP unrestricted reconstruct value := sub(0, 22)

LP unrestricted reconstruct value = -22

LP unrestricted ORIGINAL column0 := mul(22, -22)

LP unrestricted ORIGINAL column0 = -484

LP unrestricted positive column0 := mul(22, 0)

LP unrestricted positive column0 = 0

LP unrestricted negative column0 := mul(-22, 22)

LP unrestricted negative column0 = -484

LP unrestricted split column0 := sum(0, -484)

LP unrestricted split column0 = -484

LP unrestricted ORIGINAL column1 := mul(-23, -22)

LP unrestricted ORIGINAL column1 = 506

LP unrestricted positive column1 := mul(-23, 0)

LP unrestricted positive column1 = 0

LP unrestricted negative column1 := mul(23, 22)

LP unrestricted negative column1 = 506

LP unrestricted split column1 := sum(0, 506)

LP unrestricted split column1 = 506

LP unrestricted ORIGINAL column2 := mul(24, -22)

LP unrestricted ORIGINAL column2 = -528

LP unrestricted positive column2 := mul(24, 0)

LP unrestricted positive column2 = 0

LP unrestricted negative column2 := mul(-24, 22)

LP unrestricted negative column2 = -528

LP unrestricted split column2 := sum(0, -528)

LP unrestricted split column2 = -528

LP unrestricted ORIGINAL objective contribution := mul(25, -22)

LP unrestricted ORIGINAL objective contribution = -550

LP unrestricted positive objective := mul(25, 0)

LP unrestricted positive objective = 0

LP unrestricted negative objective := mul(-25, 22)

LP unrestricted negative objective = -550

LP unrestricted split objective sum := sum(0, -550)

LP unrestricted split objective sum = -550

source roles = [[22, -23, 24], 25, -22, 0, 22]

derived = [-22, [-484, 506, -528], [-484, 506, -528], 是, -550, -550, 是]
