You want to use the regexp machine to control the backtracking when searching for a Hamiltonian path? That wouldn't be something I would do, unless to as a 'proof of concept' or so.

I'd probably go for a recursive subroutine, although there's the possibility for an iterative solution as well.

As for the N-queens problem, it basically is the recursive subroutine, except molded to fit the regexp syntax. And the only reason I did this exercise was "because I can". I don't think I would easily do such a thing in production code.
