Linear programming

In a linear programming problem, the constraints represent the limitations on the situation, and the objective function is the function being maximized (or minimized). The constraints are inequalities, so a graph with all constraints shown on it will be a region, called the feasible region. The maximum or minimum value of the objective function will always happen at one of the vertices (corners) of the feasible region, so the corner points are the ones you need to check.Be sure you understand how to write constraints as well as an objective function for a real-world problem, such as one in which cost is minimized and profit is maximized. Be sure you understand how to test the vertices of the feasible region in the objective function to find the solution.
