At the #GECCO2023 closing ceremonies - really cool to see the precise calculations of GECCO's carbon footprint!

Main takeaway: In-person attendees contributed two orders of magnitude more carbon per-person than virtual attendees, almost entirely due to flights.

Dirk Sudholt is continuing the quality diversity theory theme at #GECCO2023 with a run-time analysis of QD algorithms. Really cool to see that it's possible to rigorously prove how long they should be expected to take (under controlled circumstances, including one-max and the minimum spanning tree problem)

Next up in the Theory and General Evolutionary Computation and Hybrids session at #GECCO2023, Steve Huntsman is showing some really interesting theoretical results about quality diversity algorithms!

I'll be giving my #GECCO2023 in 40 minutes (it's the first talk of the Theory and General Evolutionary Computation and Hybrids section)!

In it, I'll be talking about my work proving that calculating the probability that lexicase selection chooses a given individual is an NP-Hard problem. It's a dense topic, but my goal is to keep it accessible and give intuition behind the proof.

It's also nominated for best paper, so if you think I did a good job, I'd be honored to receive your vote 😀

#GECCO2023 Hybrid #Poster Session. Not that crowded... but I had a late start, sorry.

Currently watching the HOP track at #GECCO2023. Really interesting talk by @morenomatthewa on how different tag matching techniques affect evolvability in genetic programming systems! Turns out the choice can make a big difference.

#GECCO2023 is in a rough time zone for me (a night owl attending virtually from EDT), but I couldn't sleep last night so I caught Li Ding's excellent talk (w/ @lspector) on Probabilistic Lexicase Selection!

Main take-away: you can get comparable/better performance to lexicase selection by selecting according to (an approximation of) the same probability distribution! This also lets you adjust that probability distribution which can further improve performance.

Ended up taking an accidental social media break for a few months because I got tired of the endless LLM discourse (plus just kind of overwhelmed in general). It was nice, but I missed community and feeling in-the-loop.

Anyway, now it's conference season so I'm back! I'll probably be live-tooting #GECCO2023 and #ALife2023, so feel free to mute those hash-tags if you want to avoid the flood 😀

looking forward to sharing about evolutionary analyses comparing properties of different tag matching criteria for in exact referencing in GP (hamming, integer-based, bio-inspired, & more) at #gecco2023 HOTP

Attending #SIGEVO #GECCO2023 conference online works really well!

@caranha Hi Claus I found you on the #GECCO2023 interface asking about attendees in the Fediverse. Well here I am, probably not attending every event of the conference.

The GECCO paper submission deadline is Feb. 10th! Get those evolutionary computing papers ready! https://gecco-2023.sigevo.org/Call-for-Papers #GECCO2023
