The NP-hardness conjecture for lower oriented general position number two
Let be a graph, and let denote the minimum general position number over all orientations of . The lower-number-two hardness conjecture. It is NP-hard to decide whether
The supplied text does not provide a proof or resolution, so the complexity of this decision problem remains open.
