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. Its function is to maximize or minimize a linear objective function, subject to linear equality and inequality constraints.

What is the objective function in Linear Programming?

Back

The objective function is a mathematical expression that defines the goal of the linear programming problem, typically to maximize or minimize a quantity, such as profit or cost.

What does the feasible region represent in Linear Programming?

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.

What is the significance of corner points in the feasible region?

Back

Corner points (or vertices) of the feasible region are significant because the optimal solution to a linear programming problem will occur at one of these points.

What is a constraint in Linear Programming?

Back

A constraint is a condition that must be satisfied in a linear programming problem, usually expressed as a linear inequality or equation.

What type of line is used to represent inequalities in Linear Programming graphs?

Back

Dashed lines are used to represent inequalities that do not include the boundary (e.g., < or >), while solid lines are used for inequalities that do include the boundary (e.g., ≤ or ≥).

How do you determine the maximum value of an objective function?

Back

To determine the maximum value of an objective function, evaluate the function at each corner point of the feasible region and identify the highest value.

What is the difference between a solid line and a dashed line in a graph of inequalities?

Back

A solid line indicates that the points on the line are included in the solution set (≥ or ≤), while a dashed line indicates that the points on the line are not included (> or <).

What does it mean if a point is outside the feasible region?

Back

A point outside the feasible region does not satisfy all the constraints of the linear programming problem and is therefore not a viable solution.

What is the graphical method in Linear Programming?

Back

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