    Proof Compression and NP Versus PSPACE II: Addendum by Lew Gordeev, Edward Hermann Haeusler

    Published 2022-01-01

    Ant Colony-based Optimization algorithm to overcome the pilot contamination issue within multi-cell Massive MIMO systems by Belhabib Abdelfettah, Amadid Jamal, Khabba Asma, Zeroual Abdelouhab

    Published 2022-01-01
    “…Hence, the ACO algorithm finds for each UE its enemy UE, which leads to construct a Hamiltonian graph. This graph is exploited during the assignment of the pilot sequences to the overall UEs; specifically, the linked UEs are successively allocated with the available OPSs, which leads to address the PC problem within multi-cell mMIMO systems.…”

    Asymptotically sharpening the $s$-Hamiltonian index bound by Sulin Song, Lan Lei, Yehong Shao, Hong-Jian Lai

    Published 2022-06-01
    “…For a non-negative integer $s\le |V(G)|-3$, a graph $G$ is $s$-Hamiltonian if the removal of any $k\le s$ vertices results in a Hamiltonian graph. Given a connected simple graph $G$ that is not isomorphic to a path, a cycle, or a $K_{1,3}$, let $\delta(G)$ denote the minimum degree of $G$, let $h_s(G)$ denote the smallest integer $i$ such that the iterated line graph $L^{i}(G)$ is $s$-Hamiltonian, and let $\ell(G)$ denote the length of the longest non-closed path $P$ in which all internal vertices have degree 2 such that $P$ is not both of length 2 and in a $K_3$. …”
