Primal Formulation is a mathematical approach used in optimization problems, particularly in linear programming. It focuses on maximizing or minimizing a linear objective function subject to a set of linear constraints. The goal is to find the best possible solution within the defined limits. In linear programming, the primal formulation typically involves variables that represent the quantities to be determined. The constraints are expressed as linear inequalities, and the objective function is a linear equation. This formulation is essential for solving various real-world problems, such as resource allocation and production planning.
