We haven't determined whether there's an efficient way to solve every instance of the traveling salesman problem exactly, rather than through approximation.

open Global / Unspecified, Global

Finding the shortest possible route through many locations becomes exponentially harder as the number of locations grows, and no efficient exact solution is known for all cases. This unresolved question sits at the heart of computational optimization theory.

We don't know whether every regular geometric tiling pattern that appears possible in theory can actually be physically realized without gaps or overlaps.

open Global / Unspecified, Global

Some tiling patterns work perfectly in abstract mathematical space but haven't been proven physically constructible under all real-world constraints. This connects pure geometry with material and structural engineering.

We still haven't resolved whether it's possible to always predict the long-term behavior of any chaotic mathematical system using a finite set of rules.

open Global / Unspecified, Global

Chaotic systems are famously sensitive to initial conditions, and whether their long-term patterns can ever be fully captured by simpler predictive rules remains an unresolved question in dynamical systems theory. This has real implications for weather prediction and other complex natural systems.

We don't know whether every finite mathematical structure with a certain kind of internal symmetry must always contain a smaller, simpler symmetric structure within it.

open Global / Unspecified, Global

Ramsey-type problems ask whether order must always emerge within sufficiently large or complex systems, and while some cases are proven, the general boundaries remain incompletely mapped. This connects deeply to combinatorics and the philosophy of mathematical order.
