The Hamiltonian is exactly solved in excited states as well as doped states, including all the correlation effects.
However, finding an optimal relay subject to the three constrains is an NP-complete problem that cannot be exactly solved in polynomial time.
As for the selection of relays, in general, finding an optimal relay subject to multiple constrains is an NP-complete problem that cannot be exactly solved in polynomial time.
We show that the outer problem can be dealt with a one-dimensional search, while the inner problem admits a tight convex relaxation and hence can be exactly solved in an efficient manner.
The NP-hard class of problems contains several problems which demand for efficient alternative solutions, since there is a wide range or real-world problems which can be modeled as one of them and it is unknown if they can be exactly solved in feasible time.
As for the selection of relays, since many factors (such as distance, relative speed, and connection time between two vehicles) have influence on the selection of relays, in general, finding an optimal relay subject to multiple constrains is an NP-complete problem that cannot be exactly solved in polynomial time [11].
