Ah, the infinite #recursion of the tech world's buzzword bingo! 🤖💸 Train an AI to train AIs with RL, and somehow end up $1.3k poorer. Because who needs money when you can have infinite loops of machine learning pretense? 🙃

Recursion becomes much easier once students have the right mental model. Visualization will help get them there.

When students try to implement recursion, they often get stuck. That is where visualization can help to bring the right mental model. Tower of Hanoi example: https://www.invocation-tree.com/#codeurl=https://raw.githubusercontent.com/bterwijn/memory_graph_examples/refs/heads/main/towers_of_hanoi.py&timestep=0.5&play

Once a student can think in terms of a tree of subproblems, recursion becomes much easier to understand, explain, and debug.

JM:
❝This is a very important and interesting topic. I think you should consider the relationship to self‑reference, indeed are they really the same thing?

❝Also the work of Maturana and Varela on autopoiesis and the neurophysiology of cognition which also has recursion at its heart.❞

Thanks, John. Yes, we certainly find the whole array of self concepts coming into play here — selfhood, autopoiesis or self creation, self reference and self transformation, just to name a few. But one thing I need to emphasize from the start is how radically different such concepts appear when viewed in the x‑ray vision of Peirce’s pragmatic semiotics.

I forget where I first heard it, but it’s fairly common observation that the persistence of a recurring problem is a symptom of how unlikely it is to be solved in the paradigm where it keeps occurring.

After a while, it simply becomes time to change the paradigm …

Just by way of a first example, take the very idea of “self‑reference”. The moment we place it in the medium of triadic sign relations we realize signs do not refer to anything at all except insofar as an interpreter refers them.

And when we ask, “What is this, that we call an interpreter?”, the pragmatic theory of signs tells us we cannot tell when we turn out the light but under the x‑ray of the pragmatic maxim the sum of its effects is effectively modeled by an extended triadic sign relation.

Et sic deinceps …

Everything I’ll be working at here will be done within a framework like that.

A feature worth noting in the recursion diagram is the function traversing the square from one triadic node to the other. It preserves an image of the object n all the while its precedent p(n) is being retrieved and processed — thus it injects a measure of parallel process and a modicum of extra memory over and above that afforded by the serial composition of functions.
