You now know what linear programming is and how to use Python to solve linear programming problems. You also learned that Python linear programming libraries are just wrappers around native solvers. When the solver finishes its job, the wrapper returns the solution status, the decision variable val...

linprog() to minimize a linear objective function with linear inequality and equality constraints In practice, all of these functions are performing optimization of one sort or another. In this section, you’ll learn about the two minimization functions, minimize_scalar() and minimize(). Minimizing...
