We prove that path puzzles with complete row and column information—or
equivalently, 2D orthogonal discrete tomography with Hamiltonicity
constraint—are strongly NP-complete, ASP-complete, and #P-complete.
Along the way, we newly establish ASP-completeness and #P-completeness for
3-Dimensional Matching and Numerical 3-Dimensional Matching.
