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, often used for maximizing or minimizing a linear objective function subject to linear equality and inequality constraints.

What does 'unbounded' mean in the context of linear programming?

Back

A feasible region is unbounded if it extends infinitely in at least one direction, meaning the objective function can increase or decrease without limit.

Front

What is the feasible region in linear programming?

Back

The feasible region is the area on a graph where all the constraints overlap, representing all possible solutions that satisfy the constraints.

Front

What is an objective function?

Back

An objective function is a mathematical expression that defines the goal of a linear programming problem, typically to maximize or minimize a quantity.

Front

What are vertices in the context of the feasible region?

Back

Vertices are the corner points of the feasible region, where the constraints intersect, and potential solutions to the linear programming problem are evaluated.

Front

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

Back

To find the maximum value, evaluate the objective function at each vertex of the feasible region and identify the highest value.

Front

What is a constraint in linear programming?

Back

A constraint is a condition that the solution to a linear programming problem must satisfy, typically expressed as a linear inequality or equation.

Front

What does it mean for a solution to be feasible?

Back

A feasible solution is one that satisfies all the constraints of the linear programming problem.

Front

What is the difference between a bounded and unbounded feasible region?

Back

A bounded feasible region is enclosed and has a finite area, while an unbounded feasible region extends infinitely in one or more directions.

Front

What is the significance of the objective function's slope in linear programming?

Back

The slope of the objective function helps determine the direction in which to move to optimize the function, guiding the search for maximum or minimum values.
