That's a good point. I'm looking for highest value by the metric of something like 'weighted sum of subjective value of all problems'. Not really about a start

That's a good point. I'm looking for highest value by the metric of something like 'weighted sum of subjective value of all problems'. Not really about a start-up idea. I've been talking to a person who claims to have such an algorithm, but is looking for an actual instance of a real-world problem. So far, no one I've asked has been able to describe such a problem.
