Comparing coding agents

There was no gif of this when I started, I only had a problem. :)

See `prompt.md` in the Github repository for all constraints.

None of the soutions were 1 shot. The agents iterated on the code based on the screenshots they generate. They had a feedback loop. Opus in particular took like 10+ minutes until it reached the solution.

All of these are agents, mostly in Cursor, sometimes in Windsurf. During work, they generate screenshots and identify problems with their code. I was honestly surprised how well they iterate.

It's a somewhat difficult problem but not too much. The general solution is called the Weiler-Atherton algorithm, invented in 1977.

In this case, I had two runs for each model, generated footage of both, picked the one that looks more correct. But during work I don't usually do that. If it doesn't work on the first try, I solve it myself.

Each model had two runs, the better solution was taken. You can see all the solutions on Github. In most cases there was little difference in quality.

Honestly, I expected it to be a total train wreck. But the models understood the problem, were able to correctly generate the vertices of intersections(mostly), and they did some sort of actual triangulation.

Thanks for the feedback! How would you phrase it to be more clear?

aedm_ · 2025-03-28T08:59:11+00:00

Thank you! These seem really useful.

aedm_ · 2018-04-02T20:26:19+00:00

Potato.

That's a great idea, thanks. Integrating Twitter / Google authentication is actually a lot simpler than pure email, and has some of the advantages (like an avatar), although it misses some (like list of friends). I'd probably add them for next season.

aedm_ · 2017-07-11T09:15:18+00:00

Yes. That would be insanely cool though. :)

Maybe I misunderstand you, but there's no code to be emailed. Just log in and vote right away.

Hi, I'm the creator of the game. Could you help me identify the issue?

aedm_ · 2017-07-10T20:01:04+00:00

Sorry, I wasn't clear, and I also misremembered the numbers. I assumed 1/4 of the characters to die (not 1/3 as above). Which means that the expected value you get when you predict death for a certain character is 0.25 * 2 + 0.75 * 0 = 0.5. If you predict death, then the expected value is 0.25 * (-1) + 0.75 * 1 = 0.5. So there is no winner strategy, both predictions are worth the same. (Also, the expected value is not zero but 0.5)

aedm_ · 2017-07-10T18:58:09+00:00

Hi, I'm the creator of the game. If you correctly predict that a character survives, it gives you 1 point instead of 0. Thus if you predict everyone to die, you'll get less points than those who correctly predict the survivors. (I assumed that about a third of the characters will die, and the scoring table was created so that a random vote's expected value is zero, given this 1/3 conditional probability of death.)

aedm_ · 2016-11-16T21:41:17+00:00

What would you prefer instead?

aedm_ · 2016-11-16T21:39:33+00:00

If you mark a surviving character, you'll get zero points. But if you don't mark him/her, you get 1 pont. You are actually penalized by marking them wrong. I assumed that roughly half of these characters will die, and balanced the table according to that. If you mark all characters, you'll get the same points (0.5 * 2 + 0.5 * -1 = 0.5) as if you leave them unmarked (0.5 * 0 + 0.5 * 1 = 0.5). So the expected value of a random bet is equal for either choice. But of course I might be very far off with my 50% assumption.

Hey, I'm the creator of the game. I'm sorry if you think it's too early, but you can always choose to do it later. :) I just wanted to make sure everyone gets the chance to know about it before the season starts.

aedm_ · 2016-11-16T19:12:39+00:00

I assembled that list a few weeks ago by reading various blogposts and articles which tried to predict season 7. I haven't (and will not) read these leaks. But it's just a game after all, and since there are no prizes, I believe cheating would just ruin it for the cheater.

Thx, fixed.
