Box Folding Optimization
A piece of cardboard with a total area of 0.8m2 is to be made into an open-top box by first removing the corners and then by folding the box sides up and securing the tabs to the adjacent box side. The starting cardboard sheet has height h and width w. When cut and folded, the box has a width of w-2x, a length of h-2x, and a height of x. In order to properly secure the tabs to the adjacent box side, the width of the tab must be 5 centimeters (0.05m). The objective is to maximize the volume of the box by choosing an appropriate value of x (the height of the box) and w (the starting width of the cardboard sheet).

Python source code solves the box optimization problem with Newton's method, a quasi-Newton's method (BFGS), a steepest descent approach, and a conjugate gradient method. After the script executes, a figure appears that shows a contour plot of the solution with a graphical depiction of the progress of each method.
