Show HN: Teaching a Dinosaur to Jump: Rust, WebAssembly, and Neural Evolution

Fri, 04/11/2025 - 6:38pm

What began as a lightweight programming experiment quickly transformed into a deeply engaging technical exploration into the realms of neuroevolution, game physics, and browser-based simulation. My original goal was modest: replicate the "Chrome Dino" game using a performant and modern web stack. However, the project evolved far beyond expectations. The twist? I wanted the dinosaur to teach itself to jump.

I think I know why Collatz does that thing it does

The normal term for this is "manic delusion of grandeur", so please help me out: 3n walks congruence classes +1 steps each one out of alignment /2 never changes that fact

Accumulating co-primeness is the "memory" that stops n from repeating. This is invariant under 2^k, which allows it to make forward progress through the chaos. Exhausting congruence classes mod 3 forces n to a power of 2; game over.

I asked AI to prove those things, and it did. I assume.

The only question then would be if 1.5n can grow the residue vector quickly enough to outrun the exhaustive walk. I asked AI that too, and got back a one page p-word. I'm not even going to type it.

I can sweet-talk AI into agreeing with damned near anything, so I'm stuck. This is the only forum I know with consistently thoughtful conversation, and I can't think my way out of this one, and I have real work to do.

Is there a mathematician in the house? The p-word is in a comment.
