Defintion: Linear Programming Problem (L.P.P.)
A linear programming problem (LPP) is one that is concerned with finding the optimal value (maximum or minimum) of a linear function of several variables, subject to constraints that the variables are non-negative and satisfy a set of linear inequalities.
Maximise / Minimise:
z = c₁x₁ + c₂x₂ + ... + cₙxₙ
Subject to constraints:
a₁₁x₁ + a₁₂x₂ + ... + a₁ₙxₙ (≤, =, ≥) b₁
a₂₁x₁ + a₂₂x₂ + ... + a₂ₙxₙ (≤, =, ≥) b₂
.
.
.
... aₘ₁x₁ + aₘ₂x₂ + ... + aₘₙxₙ (≤, =, ≥) bₘ
x₁, x₂, x₃, ..., xₙ ≥ 0
Objective function:
The function z = c₁x₁ + c₂x₂ + ... + cₙxₙ is called the objective function.
