Never underestimate the power of adaptation and selection. Sub-optimizing dogs would have starved years ago.
Elvis doesn't actually do calculus. Nonetheless, Pennings remarked, "Elvis' behavior is an example of the uncanny way in which nature . . . often finds optimal solutions."
"I'd guess that most dogs have the same problem-solving software built in from the factory," he says. My article is just "drawing attention to something that has been in front of us all the while."
A LAZY CHAIN DEFINES A CATENARY CURVE. That might be an engineering maxim, or a mathematically minded economist might have said it, and it is a useful trick for designing a pottery kiln, but not a pizza oven. Now comes Elvis, the dog whose companion human, mathematician Timothy J. Pennings, wondered if he has a canine optimal pursuit algorithm.
