Linear programming.

Definition 2 A linear program (LP) is feasible if there exists a feasible solution, otherwise it is said to be infeasible. Definition 3 An optimal solution x∗ is a feasible solution s.t. cT x∗ = min{cT x : Ax = b, x ≥ 0}. Definition 4 LP is unbounded (from below) if ∀λ ∈ R, ∃ a feasible x∗ s.t. cT x∗ ≤ λ.

It is widely used in resource allocation, production planning, and logistics. Linear programming finds the best solution among viable choices using graphical and algebraic approaches. Optimal Solution: P = 3300; A = 120, B = 30, C = 0. We will maximize profit at $3300 by producing 120 units of item A, 30 units of item B, and no units of item C. In addition to maximization problems, linear programming can also be used to solve minimization problems. Linear programming, also abbreviated as LP, is a simple method that is used to depict complicated real-world relationships by using a linear function. The elements in the mathematical model so obtained have a linear relationship with each other. Linear programming is used to perform linear optimization so as to achieve the best outcome.
