Key Concepts

Linear Programming

Linear programming is a method used to achieve the best outcome, such as maximum profit or minimum cost, in a mathematical model whose requirements are represented by linear relationships. It involves optimizing a linear objective function subject to a set of linear constraints.

System of Constraints

A system of constraints in linear programming consists of multiple linear inequalities that define the conditions or limits on the decision variables. These constraints represent the restrictions under which the optimal solution must be found.

Feasible Region

The feasible region is the set of all possible solutions that satisfy all the given constraints, usually represented as a polygonal area in two-dimensional problems. It is within this region that the optimal solution is searched for.

Vertices (Extreme Points)

Vertices, or extreme points, are the intersections of the constraint boundary lines in the feasible region. According to the fundamental theorem of linear programming, if an optimum value exists, it is found at one of these vertices.

Objective Function

The objective function is the linear function that needs to be optimized, either maximized or minimized, in a linear programming problem. It represents the goal of the problem, such as maximizing profit or minimizing cost.

Graphical Method

The graphical method is a technique used to solve linear programming problems with two variables by plotting the constraints on a graph, identifying the feasible region, and then evaluating the objective function at the vertices to determine the optimal value.
