The Important Role of Linear Programming in Mathematical Modeling —— Briefly talking about the questions to be answered in the defense

Linear programming is one of the important mathematical models. But the modeling of linear programming is more representative, and its steps are clear:

1. Draw the feasible region according to the linear constraint; 2. Draw a straight line through the origin according to the objective function; 3. Move the straight line corresponding to the objective function up and down to find the optimal solution; 4. Find the maximum or minimum value of the problem.
