In what follows, I shall explain why I've been recently thinking about cats. It all started last night when my friend thought he saw a paper on my desk titled "Graph Partition by Swendsen-Wang Cats." Of course what he really saw was the paper called "Graph Partition by Swendsen-Wang Cuts." However, as he laughingly mentioned that he though I was reading on spectral graph partitioning using cats (those fuzzy cute animals), my mind rapidly explored the consequences of utilizing animals such as cats for solving difficult computational problems.
How can one use cats to solve computationally intractable problems?
Consider the problem of object recognition. The goal is to take an image, perform some low-level image manipulation and present the image to a cat. Then utilizing a system that tracks the cat's physical behavior, one needs to only map the cat's response of the visual stimulus presented into a new signal -- a solution to the more difficult problem. The hypothesis underlying the Swendsen-Want Cat Theory is that one can exploit the underlying high-level intelligence of primitive life forms to solve problems that are of interest to humans.
Thus I've been thinking about kats all of last night. I guess the word 'thinking' doesn't even do justice in this context. If anybody is interested in other (perhaps even more credible) applications of cats, I can tell them about dynamic obstacle-avoiding path planning via cats or about space exploration via colonies of ants.
