GP for the masses

My colleague Nic McPhee (with a couple of other people) is an author of a new book, A Field Guide to Genetic Programming — I think I’m going to have to read it.

Genetic programming (GP) is a systematic, domain-independent method for getting computers to solve problems automatically starting from a high-level statement of what needs to be done. Using ideas from natural evolution, GP starts from an ooze of random computer programs, and progressively refines them through processes of mutation and sexual recombination, until high-fitness solutions emerge. All this without the user having to know or specify the form or structure of solutions in advance. GP has generated a plethora of human-competitive results and applications, including novel scientific discoveries and patentable inventions.

See? It sounds cool!

Another entry in the annals of crackpottery

This is kind of sad, actually. It’s a slick website from a guy in Utah who claims to have discovered pre-Cambrian dragons. Browse around his gallery, and it’s clear that what he’s got are pictures of random rocks, and that he’s seeing shapes in them like one sees shapes in the clouds. He reminds me of Ed Conrad.

His name is Mike Hallett, so of course this period of gigantic dragons is called the Hallettstoneion. He has also written a book, which has to be seen to be believed. I swear, I think it’s actually written in crayon. Here’s a sample, in case you’d really rather not download a 40MB pdf.

Ouch. I hope his family gets the poor man some help.

Wheee, another airplane ride

In spite of all of the work piled up around me, I’m taking off today to attend the NEA/AFT Higher Education Joint Conference in Washington DC. I’m in the middle of this busy month where I spend just about every weekend flying off somewhere, in between weeks that still have the same teaching load waiting to be done.

I’m also supposed to be taped for WCCO while I’m in Minneapolis this evening, but after that, I may have to gatecrash the Minneapolis Drinking Liberally event, if it’s still going on. I hope I’m not thrown out by security.
