Looking for a (Master's?) thesis from over 20 years ago regarding the physical simulation of a frog

This is long shot.

I once read a thesis which had a very clear description of Roy Featherstone's recursive body dynamic algorithm. It was describing a bespoke physics engine used in the simulation of a frog creature, for the evolution of neural controllers for hopping. It was similar to Karl Sims' creatures, but with a fixed morphology. It was written in English, but I think it may have been a German or Dutch researcher.

It was pretty similar to (may have borrowed heavily from) Brian Mirtich's theisis on rigid body simulation.

I'd love to read it again, if anyone has any idea of what I'm talking about.

very old alife tool Framsticks that is very cool

I am surprised to learn that framsticks is still alive and kicking, and is on release 5 almost.

The website is almost dead, but I do encourage anyone who;s interested in simulating full 3d 'creatures' with various sensor types, with 'neuron networks' (to distinguish them fro mAI neural nets) used for muscle control and processing of sensory input etc.. to give it a look. It's been around for decades, and was amazing to use when I first discovered it years ago.

Community Evolution Experiment Using Lenia

Hello to anyone interested!

I've started a community evolutionary experiment Using Lenia. I've posted a short with four "creatures" I found in Lenia. In the comment section, you can vote which one is your favourite for any reason, and after enough votes are present (I would say about 10), I will breed the top two and mutate their offspring slightly. The two offspring and parents will then move on to the next round! Hopefully, we can keep this running for a while and see some exciting life forms in Lenia.

Amorphous Fortress Online

Hi everyone!

I'd like to introduce a research project my team and I have been working on that's inspired by the Sims and Dwarf Fortress: Amorphous Fortress Online. It's an open-ended multi-agent simulation / game engine where you can design FSM-based AI that interact with each other in a small environment.

It's still a work in development and the site has a user guide to help you get familiar with the interface and a feedback form to leave comments and report bugs. So far, we've published some research papers at a ALIFE 2023 workshop and in a NeurIPS 2023 workshop based on our Python version of the engine.

Check out the promo video and come design some fortresses!

"FEINE Simulation" - an evolving 2D neural network

I'm somewhat satisfied how this turned out. I had the idea only a few days ago, and now it's working better than expected. For lack of a better term it is called "Free Energy In Neuronal Evolution" FEINE Simulation (an alternative name might be "Solaris").

This is a neural network in a 2D grid (looping in both directions). Every cell is a neuron and is connected to it's neighbors. It learns nothing, but to predict itself. This is paired with simple evolution, such that cells that are activated proliferate. Out of this emerge many patterns. Waves, latices, fog, moving patches. This first version is simple. A toy model to try things.

It's interesting to watch. Shortly after the start there is a wide variety of patterns. Over time they thin out and often only one pattern is left. I'm don't know yet what is needed to have ongoing variation. Maybe for large enough simulations it would never stabilize because the spreading would not keep up with mutations.

There is one curious phenomena where cells synchronize to produce a wave of extremely high activation which cycles the world. Somewhat reminiscent of the nexus ribbon in Star Trek. This can be very stable over a long time, but sometimes it also dissipates.

Some thing I'd like to add in the future:

  • A third dimension with three layers, visualized as red green and blue.
  • Save and load function for simulations.
  • Some more use for genes.
  • Some way to combine genes and weights (similar to sexual reproduction). But what I tired so far produced gray mush.
  • Higher variety of inputs.
  • Hidden neurons for each cell.
  • Output neurons that can trigger actions.

Here are some images.

This is the third and final video on programming a simple evolutionary, ALife model using Java (Processing). It's fairly simple, but can still lead to some interesting creatures.

I thought there might be interest in this series on programming an evolutionary alife environment. It's fairly simple, but easy to expand.

Simulation of evolution. Today we will analyze one of the simulations where life managed to survive in cyclic form. Now I am more inclined not to the evolution of individual species, but to the entire biosphere and its search for a stable state.

Storytelling AI?

Looking for an AI which can write long pieces or even entire chapters after giving them a world, event and character personalities to work with. This is purely just for my own enjoyment, like reading fanfic basically.

Willing to use a paid program. Right now GPT really isn't cutting it.

Any good AI translators?

What is a good AI for translating?

Hello!

Recently got a job offer for a video editor position! I would be doing video edits for clients that want to push shorts on social media.

Most of the videos will be in Dutch (a language I do not speak) and they will require subtitle in Dutch too. The built in subtitle generator in Premier is not the best.

I am looking for a way around it and thinking that maybe translating the transcript on the internet and checking possible mistakes would be a way to do it. Maybe there are more elaborate ways, perhaps using AI that would do audio to text translation. Any suggestions?

What do you honestly think about this?

Yo,

so, I'm having somewhat of a crisis, due to a lot of personal reasons, one being professional. I am an undergrad in applied mathematics. Lots of people graduating and going to work with data or software engineering. I don't feel like doing any of it. Actually, I kinda know what I'd like to do. I'd like to write stuff like this. But I'm not sure if that's, like, job-worthy? To be clear, I'm making this post here specifically because this text was written for an essay contest at ALIFE2021.

I also sent it to a professor. He said that "it looks like philosophy with some non-trivial mathematics". I took it as a compliment, because it's kinda precisely what I wanted (it was an essay, after all). But does that count as research? Does that somehow produce meaningful knowledge? If so, where do people value that kind of work? What and where should I aim?

Naturally, this essay was too shallow, scientific-research-wise; there was much more to explore, but I think it gives a general idea of the path I'd like to take.

I was afraid of being misunderstood in my intentions or exposing myself too much. I confess I didn't read the rules, so, if I did anything inappropriate by writing this post, I apologize in advance and ask the mods to please delete this post.

And about exposing myself, I do believe the alife community is very, uh, receptive.

aLife simulation

https://reddit.com/link/17aq6d1/video/qan621fwkyub1/player

Map of the "organic" content in the soil during the aLife simulation.The darker, the more “organic”.Red zones are an overabundance of organic matter; life is impossible in this place.Organic matter remains in the soil after organisms die.Some species can feed on organic matter.Photosynthesis also depends on the amount of organic matter. The more organic matter there is at a given point, the more energy a photosynthetic organism can receive from the Sun.The video shows a quick rewind of a long simulation.

This is an attempt at an evolutionary version of particle life - clusters of particles that evolve their own internal and external sets of rules to try to out compete each other. Does anyone know of other evolutionary versions of particle life?

Simple flocking simulation in a high-level javascript library called p5play

I'm having fun exploring the very nice javascript library p5play: https://p5play.org/ . It combines the user-friendly graphics of p5js with built-in sprites, collision-detection & a physics engine. Should be good for making math games. Here's a simple flocking sim: https://rajeevraizada.github.io/flocking_p5play/
