I Made a Website for Problems▲107
Hey everyone! While searching for entrepreneurial ideas on various sites, I noticed there wasn’t a dedicated space for finding and discussing real-world problems that need solving. That’s why I created the Problem Platform—a place where we can share, explore, and tackle problems together. Check it out!

Monty's Gauntlet – Do You *Really* Understand the Monty Hall Problem?▲9
A variant of the Monty Hall problem (the 7th one on this quiz) went semi-viral a couple months ago. For me at least, I may be able to walk through the reasoning of the original problem, and I may be able to convince myself it's correct, but it's very hard to build an intuition for why it's correct that feels truly sound. So I thought it'd be interesting to have a quiz to contort the original problem in as many ways as possible to challenge my understanding and intuition. Try it out!

I built an AI that uses a metacognitive loop 2 solve invention problems▲9
Hi HN, I'm the creator of this project. For the past months, I've been working on building an AI agent that could move beyond simple generation and tackle inventive challenges autonomously. The core idea was to create a system with a "metacognitive loop"—the ability to recognize when it's stuck on a fundamental problem and then launch a sub-mission to solve that specific bottleneck before continuing. The linked article is a deeper introduction to the system's architecture and a snapshot from a recent run. I tried to design it to be evidence-grounded and self-critical to avoid the pitfalls of…
