Abstract In this article, we present the process and results of using quantum computing (QC) to solve maximal covering location problem proposed by Church ReVelle. With contribution, seek lay foundations for other urban regional scientists begin consider technologies. We obtained promising results, but it is clear that there a need more capable devices with qubits less susceptibility electronic...

We determine the minimal covering of maximal partial clones in 4-valued logic. That means a necessary and sufficient condition for partial Sheffer functions in 4-valued logic in terms of the maximal partial clones is established. Furthermore several statements about members of the minimal covering of the maximal partial clones for any finite-valued logic are established.
