What is an objective function in a linear programming problem?

Short Answer

Expert verified
In a linear programming problem, an objective function is the function that needs to be optimized (maximized or minimized). It quantitatively represents the goal of the problem, in terms of decision variables.

Step by step solution

01

Define Linear Programming

Linear programming is a mathematical optimization technique for a system of linear constraints and a linear objective function.
02

Introduce Objectives

Linear programming problems often involve an objective, which is the goal an organization or individual wants to achieve. This can be maximizing profit, minimizing cost, or reaching a specific operational level.
03

Explain the Objective Function

The objective function quantifies the objective, representing it as a mathematical equation. In a linear programming problem, the decision variables in this equation are manipulated to find the optimal solution. For instance, if an organization aims to maximize profit, the objective function might be the total revenue minus total cost. The task is to manipulate the variables that affect profit (like production levels) so as to maximize this function.

Determine whether each statement makes sense or does not make sense, and explain your reasoning. Even if a linear system has a solution set involving fractions, such as \(\left\\{\left(\frac{8}{11}, \frac{43}{11}\right)\right\\},\) I can use graphs to determine if the solution set is reasonable.

Perform the operations and write the result in standard form: $$\frac{-20+\sqrt{-32}}{10}$$
