Understanding Linear Programming and Its Importance
What Is Linear Programming?
Linear programming (LP) is a mathematical technique used to optimize a linear objective function, subject to a set of linear inequalities or equations called constraints. It is widely applied in various fields such as operations research, economics, manufacturing, transportation, and finance to maximize profits, minimize costs, or achieve the best possible outcome within given limitations.

Practicing solved problems is crucial for grasping the intricacies of linear programming. It helps in:
- Understanding the step-by-step approach to formulating problems
- Learning how to identify decision variables and constraints
- Mastering the graphical and algebraic solution methods
- Building problem-solving speed and accuracy
- Preparing effectively for examinations and professional assessments
