I am … unhindered by talent

When I fly to conferences I tend to take the low cost carrier, whatever that happens to be. Much of the cost is coming out of my pocket, and I’m cheap (’cause the conferences never are). For GECCO [1], AirTran was the winner, with a price a hair under $200 round trip, which was quite a lot less than I was expecting to pay for the flight. One little tidbit I didn’t really appreciate until several weeks after I booked the flight was that AirTran flies out of the Hubert H. Humphrey (HHH) terminal of the Minneapolis-St. Paul (MSP) airport, and I’m currently adrift in the empty, echoing terminus of HHH with a handful of fellow travelers.

For those unfamiliar with MSP, the vast majority of flights use the Lindbergh terminal, and I suspect many people pass through MSP with nary a clue that the Humphrey terminal exists. I think I’ve only flown through HHH once before, on a Sun Country flight to a conference several years ago, and I’d pretty much forgotten what it was like over here.

I knew I’d have a couple of hours to kill at the airport between the arrival of my shuttle from Morris and my departure, and I figured I’d grab some lunch and try to continue revising our GECCO talks. This, however, failed to take into account my departure from the Humphrey terminal instead of Lindbergh. The Lindbergh terminal is a nice airport, with lots of restaurants (some of which are pretty decent) and even a passable book store or two. HHH is a small terminal (10 gates) servicing a ragtag group of low cost and limited traffic airlines.

It’s like a ghost town, but with airplanes.

There was almost no one here when I arrived. Only one of the dozen or so AirTran desks was open, there were no customers in sight, and I was able to just walk right up. Security also only had one queue open, but there were only four or five of us going through at the time, so it was again “Step right up and off you go”. The waiting areas were almost completely empty when I got here, and now (probably 30-40 minutes away from boarding) have a smattering of folks.

All this is most definitely to the good, especially when compared to some of the chaotic and stressful check-ins and security checks we’ve had in some of our recent flights.

The downside is that there are pretty much zip in the way of services or staff. There are a whopping two coffee/sandwich shops in the whole terminal, one on either side of security, and one bar/restaurant. After that we’re down to a magazine rack and a few vending machines. And the coffee shop inside of security didn’t have anyone at the till when I first came through.

Arguably less good, and certainly weird. No one’s going to mistake it for Heathrow or O’Hare, I promise you.

The real bummer, of course, is that there’s no free wifi here (or at the Lindbergh terminal). $4.95 for an hour, or $7.95 for the day.

Wonderful. Almost as wonderful as the fine $3 sandwich that cost me $7 for when the coffee shop finally opened up.

I’m looking forward to not flying for quite a while (perhaps as much as a year!) after I return from this trip. It’s nice being other places, but getting there isn’t always loads of fun, and it tends to suck environmentally.

¹ GECCO = Genetic and Evolutionary Computation Conference, one of the two or three big international “mega” conferences in evolutionary computation. To be honest GECCO is much bigger and more circus-like than would be my preference. I’m much happier at smaller gigs like EuroGP, but that’s during the school year, and at an awkward time, and a lot more expensive to get to, so I’ve attended a lot more GECCOs than EuroGPs :-(.

As mentioned earlier, our paper “Semantic building blocks in genetic programming” with Brian Ohs (UMM ‘08) and Tyler Hutchison (UMM ‘07) was nominated for Best Paper at EuroGP 2008 in Naples, Italy.

We won!

That a paper co-authored with two undergraduates from a small, public, undergraduate liberal arts institution like the University of Minnesota, Morris, could win an award like this at an international science conference is just too damn cool. Well done to both Brian and Tyler!

In the hectic melee of the conference, most folks don’t have time to do anything more than skim the nominated papers, and usually not even that. This makes the talks a crucial part of an award like this, as much of the voting is based on them. Tyler (pictured above at Castel dell’Ovo in Naples) was a huge help in that regard. He flew over to the UK several days early so we could work on our talk, giving us the time we needed to revise and practice. He also produced a super cool little six page comic with a nifty introduction to our work that the audience could follow along with. We did a joint presentation, each covering about half the paper. Our talk was well received, and Tyler’s comic was incredibly (and deservedly) popular, and there’s no doubt that his participation was a huge help.

(And all this is on top of Brian and Tyler’s hard work and contributions on the paper itself. Obviously without that content we never would have had the paper accepted or nominated in the first place. So they both deserve huge kudos for that as well.)

Friday morning our paper was voted Best Paper by the conference attendees, and we were presented with a certificate, a box of Italian lemon cookies, and a box of Irish chocolates. All the Best Paper winners from the various EvoStar conferences and workshops also got to choose a free book from the Springer table. Tyler got a really cool book enitled Leonardo’s Lost Robots, and I got The forgotten revolution: How science was born in 300 BC and why it had to be reborn. (It was all terribly liberal arts of us - pretty much everyone else took evolutionary computation/artificial intelligence books of one form or another.)

Tyler upheld a fine tradition of our students making UMM look really good at conferences like this. From his deportment and grasp of the material, most people assumed he was a graduate student, despite the fact that the looks like he’s about 16 :-). He’s currently doing contract work as a web developer and designer, but is seriously interested in going to graduate school in the near future, and he definitely impressed the folks at the conference. I’ve been really lucky to work (and co-publish) with a string of great UMM students, and am looking forward to continue that with a very sharp student named Sara Lahr when we get back.

The trick for me (sometimes) is remembering just how good our students can be. The room we spoke in was this grand space of inlaid wood and marble that was quite a surprise in several ways. This was made worse by the fact that we were in the first session, so we had very little time to adjust and adapt. I was worried about running long (we had a lot of material to cover), and started to lose my nerve about having Tyler wandering around the room at the beginning handing out the comic. Tyler was really calm and collected about it, though, talked me down, and everything did in fact go really smoothly. The moral? Handouts are Good, really cool comics handous are Even Better, and I need to remember to listen to my students :-).

Thanks a ton to Brian and Tyler and all the people and offices at UMM that supported our work, and everyone who voted for our paper at EuroGP! Special thanks also to Riccardo Poli for hosting me on this sabbatical at the University of Essex. I’ve gotten a ton of cool work done here with Riccardo, including “A linear estimation of distribution GP system” at EuroGP, which was also nominated for Best Paper (and which I suspect was also strongly in the running).

I’ve dumped all the photos Tyler and I took in Naples onto my events account on Flickr. I’ll try to clean up a few to post to my main Flickr account in the next week or so.

I’ve been sitting on this for a while I waited for EuroGP to get their web site updated; they have, freeing me up to do a little unabashed chest-thumping, leavened with some praise for UMM’s excellent students.

A few weeks from now the Eleventh European conference on Genetic Programming (EuroGP) will happen in Naples Italy. The only other time I’ve been to EuroGP was in 2001 when we were here on sabbatical the first time. I really love the conference, and it’s small and intimate and tends to have a really high signal-to-noise ratio. Unfortunately, it’s also an expensive flight from Minnesota for a three day event, and the timing tends to be really awkward in my teaching schedule, so I’ve never made it back. One of my many fond memories of that conference was winning the best paper award with Riccardo Poli for a pair of papers we’d written together as part of that sabbatical visit. (Oddly, both times I’ve attended have happened to be the only two times it’s been in Italy. The little photo is from the 2001 event at Lake Como.)

The best paper nominations for this year’s event have been released, and I’m quite excited that both of the papers that I submitted this year are on the list. One is another join project with Riccardo, and the other is a paper with two UMM undergrads: Brian Ohs and Tyler Hutchison.

That’s Tyler in the photo up top, presenting some work he did with Andy Korth and I that won the best student paper award at MICS a year ago; Tyler also did the cover illustration for the forthcoming book Riccardo, Bill Langdon, and I are just wrapping up. In a big happy, Tyler was able to pull together the funds to fly out for the conference, so we’ll be able to do a joint presentation enlivened by his presence and cool drawings. Unfortunately Brian can’t make it, but it’s cool that Tyler can; this will be the first of my students co-authors that’s made it to a European conference with me.

The competition is gonna be tough for the best paper award, including a very nice paper by one of Riccardo’s students (Stephen Dignum). Fingers crossed!

The full program is also now on-line (as a PDF) — it looks like some cool material. I’m quite looking forward to the conference, although I must say I’m a bit nervous about the ongoing trash crisis in Naples (here and there).

Sometimes you’re just minding your own business, trying to get a little science done, and a little art pops out at you all unexpected.

What?!? You want to know where this comes from? All is revealed beneath the fold…

It’s pretty cool when you update your repository and see

At revision 400

We just hit that on the genetic programming book that Riccardo and Bill and I are working on; we’re currently averaging close to 10 commits a day here in the final stages. We hope to wrap it up in the next 1.5 weeks and then off to the printers for fun (and no profit in the traditional sense)!

P.S. Anyone want to proof read a few pages? Get in touch and we can work something out.

Just finished my GECCO reviewing, and I must say that is seriously sucks when people don’t attend to even the most basic of issues. Two things almost guaranteed to majorly annoy a reviewer:

• Weird random floating fragments of text that are obviously the disemboweled remnants of some cut and paste action.
• Only 8 entries in the bibliography on a subject that has been heavily researched for over a decade.

And just guess the average publication date of 8 fine references.

1985.

Yeah, over 20 years ago.

3 entries were books (two of which were over 10 years old), and the only 2 journal articles were from 1938 and 1964 respectively.

Strangely enough, I didn’t encourage acceptance of that paper.

The really depressing thing is that most of our (undergraduate) students at UMM would do better than this.

No, maybe that’s the uplifting thing.

Maybe the really depressing thing is that I see papers with this kind of bibliography fairly often. I’d almost recommend some sort of automatic rejection system for obviously stupid bibliographies, but then people would just start padding their bibliographies with random citations to get past that blockade.

Sigh.

Chris posted some cool questions on my earlier post about decentralized behavior in social insects:

so what kinds of things do computer scientists do w/this idea? is sort of what evolutionary computing is about? i picked up the evolution of cooperation recently (tit for tat wins prisoner’s dilemma) you must be familiar w/this, yes?”

There’s really three different (but related) ideas in this question:

• Decentralized and emergent behavior
• Evolutionary computation
• Game theory and cooperation

I’ll take them one at a time, with more on the first of the three, at least for now.

All good things must come to an end, and our week at Dagstuhl ends tomorrow after lunch. Above is yesterday’s group picture (I’m in yellow near the front) just before the traditional Wednesday hike (below), which was wet and misty but still an enjoyable few hours out in the world.

I gave a talk this morning which (I think) went well, especially since I didn’t know I was going to be giving a talk until Tuesday afternoon! There was certainly a lot of good discussion and people came up with tons of suggestions and ideas, which is what I really love about presenting at Dagstuhl. I started with something quite fun, which I’ll post here later. Most of the talks have used computer slides (PowerPoint or some more sensible alternative like LaTeX/Beamer), but Jon Rowe did a great blackboard talk on Tuesday (pictured below).

I was greatly inspired and did almost all of mine on the boards as well. I had four slides at the beginning that really needed to be slides, and then I did the bulk on the boards, and came back to a fifth slide at the end.

Tomorrow there are talks before lunch, including a talk/discussion thing that Riccardo is doing that I’m sure I’ll be roped into in some mysterious way. Then we eat, and it’s a taxi out to the Frankfurt Hahn airport for our flight back to the UK!

JOCP! It’s been almost five days since I’ve posted anything here, and I have so much backed up in the queue…

There’s a major conference deadline (GECCO 2008) in a few days, and I’m struggling to finish up four different (and only loosely related) papers for submission. On top of that I leave Sunday morning for an excellent week in Germany at a research seminar at the wondrous Schloss Dagstuhl. (Feel free to visit some of my photos from my last visit to Dagstuhl.)

So sleep is short and fun on the blog is shorter still. In two weeks, though, I should be able to get back in the game a bit.

The top photo is of a student (Tyler - now graduated) during a talk he was giving with another student (Andy) at a regional computer science conference (MICS) last April. On the next day the two of them received the best student paper award for this work :-).

I’ve spent numerous hours this week drawing and redrawing graphs and tables, so this is all too reminiscent of my life at the moment.

The photo below is from a beautiful snowfall we had during the Dagstuhl workshop two years ago.
