Formulas

Fungsi tujuan: z = 2x1 + 3x2 - 5x3 (maksimum)
Kendala: x1 + x2 + x3 = 7, 2x1 - 5x2 + x3 >= 10
Big M Penalty: Z = 2x1 + 3x2 - 5x3 - M(R1 + R2)

Theorems

Simplex Method Theorem: To optimize a linear objective function subject to linear constraints.
Big M Method: Uses large penalty M to handle artificial variables in linear programming.
