Thanks to Magnus's issue reporting!
To reproduce the issue
The cause of the issue
A bug in the solver.
At each step of the annealing process, the solution was immediately rejected if it did not satisfy the constraints, and thus the solver was stuck in an infinite loop without reaching a valid solution.
How to resolve the issue
Solutions that does not satisfy the constraints can be allowed in the earlier annealing steps, and the constraints will eventually satisfied in the final step.
I'll release a next version in a few days.
