I think the constraints have not one solution. E.g. multiple overlapping polygons in 2D, how would you resolve that globally in a way such that the solution converges to the physical solution?

Yup you can construct constraints such that they are impossible to solve. Solving using global methods can also end up in cases where the solver is going to take to long to solve for the simulation to remain real-time. Lots of trade offs to make based on what you’re trying to do.
