World Solve — A living repository of problems worth solving.

What World Solve is

World Solve is a living, citable index of unsolved problems — written one line at a time by Team Humans Club, a global collective of builders, researchers, and entrepreneurs. We do not solve the problems here. We Democratize Innovation.

For buildersSkip the search for a problem worth your time. Browse a vetted, growing list and start where the gap is real.

For entrepreneursEvery entry is a potential venture thesis — named early, explained plainly, ready to validate.

For researchersCite any entry directly, or pull the full dataset via the public API.

We don't know whether the exact boundary between solvable and unsolvable optimization problems can be mapped with full precision for every possible problem type.

open Mathematics & Logic

Some optimization problems are proven solvable efficiently, others proven intractable, but a complete boundary map covering every conceivable variation remains incomplete. This unresolved question is central to computational complexity theory.
