Since the printer head broke during my first attempt at printing a 3D model, I took the opportunity to adjust my graph to something more interesting.
I showed my previous attempt to a few colleagues and students. One former student told me it would be very helpful for him to see this model in class when we were covering the topic of the path of steepest ascent. Another professor suggested I tweak the surface to include multiple relative maxima that have different heights. Here’s what I came up with.
In 12 hours, I’ll go back to the printer to see the result.
