The objective function in a linear programming problem specifies the aim that must be maximized or minimized in terms of a certain quantity, such as profit, cost, or efficiency. The relationship between the decision-making factors and the desired result is expressed mathematically in this way. The objective function's job is to lead the problem toward the optimal solution achievable within the system's limitations. It does this by assisting in the identification of the set of variable values that, when combined, would produce the optimum outcome while continuing to adhere by the constraints.
