What is a chemlambda quine?

UPDATE 3: I made a landing page for my pages to play and learn.

UPDATE 2: And now there is Fractalize!

UPDATE: The most recent addition to the material mentioned in the post is Find a Quine, which let you generate random 10 nodes graphs (there are 9 billion of them) and to search for new quines. They are rare, but today I found 3 (two all of them are shown as examples).  If you find one, mail me the code (instructions on the page).

The ease of use of the recently written chemlambda.js makes easier the sharing of past ideas (from the chemlambda collection) and as well of new ideas.

Here is some material and some new thoughts. Before this, just recall that the *new* work is in hapax. See what chemlambda has to do with hapax, especially towards the end.

A video tutorial about how to use the rest of new demos.

The story of the first chemlambda quine, deduced from the predecessor of a Church number. Especially funny is that this time you are not watching an animation, it happens in front of you 🙂

More quines and random eggs, if you want to go further in the subject of chemlambda quines.  The eggs are 4-nodes graphs (there are 720 of them). They manifest an amazing variety of behaviour. I think that the most interesting is that there are quines and there are also graphs which have a reversible evolution, without being quines. Indeed, in chemlambda a quine is one which has a periodic evolution (thus is reversible) under the greedy algorithm of rewrites. But there is also the reversible, but not quine case, where you can reverse the evolution of a graph by picking a sequence of rewrites.

Finally, if you want to look also at famous animations, you have the feed the quine. This contains some quines but also some other graphs which featured in the chemlambda collection.

Most of all, come back to see more, because I’m going to update and update…
