Use mode=minimize, coefficients=[12, -13, 1], rhs=0. The fixed target convention is maximize/≤/nonnegative. Give (mode, objective_coefficients, maximization_coefficients, conversion_rule, optimality_certificate, boundary).
G001 — Use mode=minimize, coefficients=[12, -13, 1], rhs=0. The fixed target convention is maximize/≤/nonnegative. Give (mode, objective_coefficients, maximization_coefficients, conversion_rule, optimality_certificate, boundary).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
source roles = [lp-standard-convention-boundary]
After
derived = [[mode, objective_coefficients, maximization_coefficients, conversion_rule, optimality_certificate, boundary]]
Conditions: none
List the full source field order without JavaScript.LP boundary modes all have6 fields but select different roles from the original mode,not answer shape.

Before
LP convention coefficient0 negation := mul(-1, 12)
After
LP convention coefficient0 negation = -12
Conditions: none
Substitute original roles and established intermediates exactly,without rounding or substituting a single observation.
Rule: exact_rational_arithmetic · Uses: G001, S001
Before
LP convention coefficient1 negation := mul(-1, -13)
After
LP convention coefficient1 negation = 13
Conditions: none
Substitute original roles and established intermediates exactly,without rounding or substituting a single observation.
Rule: exact_rational_arithmetic · Uses: G001, S002
Before
LP convention coefficient2 negation := mul(-1, 1)
After
LP convention coefficient2 negation = -1
Conditions: none
Substitute original roles and established intermediates exactly,without rounding or substituting a single observation.
Rule: exact_rational_arithmetic · Uses: G001, S003
Before
source roles = [minimize, [12, -13, 1], 0]
After
derived = [minimize, [12, -13, 1], [-12, 13, -1], negate_objective_to_convert_minimize_to_maximize, No, conversion_does_not_prove_feasible_bounded_or_optimal]
Conditions: none
Multiplying a >=constraint by−1 reverses its sign;equality is two opposite <=constraints;minimizing cTx is maximizing(−c)Tx with negated value.For minimize,rhs0 is only an unused-field sentinel.Conversion preserves pointwise constraints/objectives,not feasibility,boundedness,existence of an optimum or duality;no b>=0 assumption.

S005 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S004 · premise_and_result_audit — Recompute LP convention coefficient2 negation with exact rational arithmetic, not rounded decimals.S003 · premise_and_result_audit — Recompute LP convention coefficient1 negation with exact rational arithmetic, not rounded decimals.S002 · premise_and_result_audit — Recompute LP convention coefficient0 negation with exact rational arithmetic, not rounded decimals.S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.(minimize, [12, -13, 1], [-12, 13, -1], negate_objective_to_convert_minimize_to_maximize, No, conversion_does_not_prove_feasible_bounded_or_optimal)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
