What is Linear Programming?

Back

Linear Programming is a mathematical method for determining a way to achieve the best outcome in a given mathematical model. It involves maximizing or minimizing a linear objective function, subject to linear equality and inequality constraints.

Front

What are constraints in Linear Programming?

Back

Constraints are the restrictions or limitations on the variables in a linear programming problem. They define the feasible region where the solution must lie.

Front

What is a feasible region?

Back

The feasible region is the set of all possible points that satisfy the constraints of a linear programming problem. It is typically represented graphically as a polygon.

Front

What is an objective function?

Back

An objective function is the function that needs to be maximized or minimized in a linear programming problem. It is usually expressed in terms of the decision variables.

Front

How do you identify corner points in a feasible region?

Back

Corner points, or vertices, of a feasible region can be identified by finding the intersection points of the constraint lines on a graph.

Front

What is the significance of corner points in Linear Programming?

Back

Corner points are significant because the optimal solution to a linear programming problem will always occur at one of the corner points of the feasible region.

Front

What does it mean to maximize an objective function?

Back

To maximize an objective function means to find the highest possible value of the function within the constraints of the problem.

Front

What does it mean to minimize an objective function?

Back

To minimize an objective function means to find the lowest possible value of the function within the constraints of the problem.

Front

What is the graphical method in Linear Programming?

Back

The graphical method is a way to solve linear programming problems by graphing the constraints, identifying the feasible region, and evaluating the objective function at the corner points.

Front

What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities that involve the same variables. The solution is the set of points that satisfy all inequalities simultaneously.
