Robotics and Artificial Life

Today I received an email from someone who enjoys my Artificial Life iPhone app. He included a link to an interesting article about an evolutionary robotics experiment in Switzerland that is somewhat similar in concept to what I am trying to do with my app - start with random behaviors and see what useful behavior evolves over time.

Here's a link to the article:

If you like artificial life and AI systems, it's an interesting read.

Some time ago I downloaded your application, "Artificial life". It is very well done and quite entertaining. At first the simple game of changing the various settings to see the results was enough. Extreme close-ups of the world gave very different pictures, sometimes colorful ones, with a lot of action. Then my interest shifted to imposing extreme conditions on the protozoa to see how they would adapt. That's when I noticed that population growth was not quick. So the game became a challenge to find conditions which would allow for the population to reach the maximum of 300. Then what? I don't know yet. The experiment is still going on! Perhaps the population will decrease again, before making a come back?

A few suggestions, in case you plan to add to "Artificial life". New genes: Increase/decrease speed (to a certain limit, when a certain condition is met). "Join" other protozoa or "aggregate" if a certain condition is met. At birth: Gain or lose the capacity for gaining or losing 1 chromosome at birth (protozoa with different numbers of chromosomes cannot mate); attack attacker...

Why not give a little mass to the protozoa and their corpses?

One thing that's missing from the game: The protozoa have no way to influence their environnement. What if they excreted something, one of various substances?

A special information panel would be nice: World age (since the latest world modification). Average distance of the protozoa from the sun. Farthest protozoa (some of them gather very far from a deadly sun...) Color distribution. Most present gene...

The music is quite good too!
